HX6408  
512K x 8 STATIC RAM  
The monolithic 512K x 8 Radiation Hardened Static  
RAM is a high performance 524,288 word x 8-bit  
static random access memory. It is fabricated with  
Honeywell’s radiation hardened technology. It is  
QML qualified and is designed for use in systems  
operating in radiation environments. The SRAM  
operates over the full military temperature range and  
requires only a single 3.3V power supply. The SRAM  
is available with CMOS compatible I/O. Power  
consumption is typically 710mW at 40MHz operation  
and less than 5mW when de-selected.  
SRAM  
operation is fully asynchronous, with a typical access  
time of 20ns. It is available in package and known  
good die forms.  
The memory cell is single event upset hardened,  
while multi-layer metal power busing and small  
collection volumes of SOI provides superior single  
event effect and dose rate hardening.  
Honeywell’s enhanced SOI RICMOS™ V (Radiation  
Insensitive CMOS) technology is radiation hardened  
through the use of advanced and proprietary design,  
layout, and process hardening techniques. The  
RICMOS™ V low power process is a 3.3V, SOI  
CMOS technology with an 80 angstrom gate oxide  
and a minimum drawn feature size of 0.35um.

RADIATION CHARACTERISTICS  
Total Ionizing Dose Radiation  
data during and after exposure to a transient dose  
rate ionizing radiation pulse, up to the DRU  
specification. The SRAM will also meet functional and  
timing specifications after exposure to a transient  
dose rate ionizing radiation pulse up to the DRS  
specification.  
The SRAM radiation hardness assurance TID level  
was qualified by 60Co testing, including overdose and  
accelerated annealing, per MIL-STD-883 Method  
1019. Ongoing assurance is provided by wafer level  
X-ray testing during manufacturing.  
Single Event Soft Error Rate  
Neutron Irradiation Damage  
Special process, memory cell, circuit and layout  
design considerations are included in the SRAM to  
minimize the impact of heavy ion and proton radiation  
and achieve small projected SER. These techniques  
sufficiently harden the SRAM such that cell  
redundancy and scrubbing are not required to  
achieve the projected SER.  
SOI CMOS is inherently tolerant to damage from  
neutron irradiation. The SRAM meets functional and  
timing specifications after exposure to the specified  
neutron fluence.  
Latchup  
The SRAM will not latchup when exposed to any of  
the above radiation environments when applied  
under recommended operating conditions. SOI  
CMOS provides oxide isolation between adjacent  
PMOS and NMOS transistors and eliminates any  
potential SCR latchup structures.  
Transient Dose Rate Ionizing Radiation  
Many aspects of product design are addressed to  
handle the high energy levels associated with the  
transient dose rate events. This allows the SRAM to  
be capable of writing, reading, and retaining stored

FUNCTIONAL DESCRIPTION  
SRAM Operation  
Address transition. The NCS/NSL active transition  
can occur later; however, the valid Data Output (Q)  
access time will then be defined by TSLQV/TPHQV  
instead of TAVQV. To perform consecutive read  
cycles, NCS/NSL is held continuously low/high, and  
the toggling of any Address will start a new read  
cycle. Any amount of toggling or skew between  
Address transitions is permissible; however, Data  
Output will not become valid until TAVQV following  
the last occurring Address transition. The minimum  
Address activated read cycle time is TAVAVR which  
is the time between the last Address transition of the  
previous cycle and the first Address transition of the  
next cycle. The valid Data Output from a previous  
cycle will remain valid until TAXQX following the first  
Address transition of the next cycle.  
SRAM operation is asynchronous. Operating modes  
are defined in the Truth Table. Read operations can  
be controlled by Address (A), Sleep (NSL) or Chip  
Select (NCS). Write operations can be controlled by  
Write Enable (NWE), Sleep (NSL) or Chip Select  
(NCS).  
Read Operation  
A read operation occurs when Chip Select (NCS) is  
low and Sleep (NSL) and Write Enable (NWE) are  
high. The output drivers are controlled independently  
by the Output Enable (NOE) signal.  
To control a read cycle with NCS/NSL where  
TSLQV/TPHQV is the access time, all addresses  
must be valid TAVQV minus TSLQV/TPHQV prior to  
the enabling NCS/NSL transition. Address transitions  
can occur later; however, the valid Data Output (Q)  
access time will then be defined by TAVQV instead of  
TSLQV/TPHQV. NCS/NSL can disable the read at  
any time; however, Data Output drivers will enter a  
High-Z state TSHQZ/TPLQZ later.  
Write Operation  
A write operation occurs when Write Enable (NWE)  
and Chip Select (NCS) are low and Sleep (NSL) is  
high. The write mode can be controlled via three  
different control signals: NWE, NCS or NSL can start  
the write mode and end the write mode, but the write  
operation itself is defined by the overlap of NWE low,  
NCS low and NSL high. All three modes of control  
are similar, except the NCS and NSL controlled  
To control a read cycle with Address where TAVQV  
is the access time, NCS/NSL must transition to active  
TSLQV/TPHQV minus TAVQV prior to the last

HX6408  
modes deselect the SRAM when NCS is high or NSL  
is low between writes.  
Consecutive write cycles are performed by toggling at  
least one of the start of write control signals for  
TWHWL/TSHSL/TPLPH. If only one of these signals  
is used, the other two must be in their write enable  
states. The minimum write cycle time is  
TAVAVW/TAVAVS/TAVAVP.  
To write Data (D) into the SRAM, NWE and NCS  
must be held low and NSL must be held high for at  
least TWLWH, TSLSH and TPHPL respectively. Any  
amount of skew between these signal transitions can  
be tolerated, and any one of these control signals can  
start or end the write operation as long as there is  
sufficient overlap in these signals to ensure a valid  
write time (e.g., TSLWH, TWLSH, TPHWH and  
TWLPL).  
Signal Integrity  
As a general design practice, one should have good  
signal integrity which means input signals that are  
free of noise, glitches and ringing with rising and  
falling edges of ≤10ns. More specifically, an input is  
considered to have good signal integrity when the  
input voltage monotonically traverses the region  
between VIL and VIH in ≤10ns. This is especially  
important in a selected and enabled state. When the  
device is selected and enabled, the last transitioning  
input for the desired operation must have good signal  
integrity to maintain valid operation. The transitioning  
inputs that bring the device into and out of a selected  
and enabled state must also have good signal  
integrity to maintain valid operation. When the device  
is deselected and/or disabled, inputs can have poor  
signal integrity and even float as long as the inputs  
that are defining the deselected and/or disabled state  
stay within valid VIL and VIH voltage levels.  
However, floating inputs for an extended period of  
time is not recommended.  
Address inputs must  
be valid  
at  
least  
TAVWL/TAVSL/TAVPH before the start of write and  
TAVWH/TAVSH/TAVPL before the end of write and  
must remain valid during the write operation. Hold  
times for address inputs with respect to the end of  
write must be a minimum of TWHAX/TSHAX/TPLAX.  
A Data Input (D) valid to the end of write time of  
TDVWH/TDVSH/TDVPL must be provided during the  
write operation. Hold times for Data Input with  
respect to the end of write must be at least  
TWHDX/TSHDX/TPLDX. To avoid Data Input driver  
contention with the SRAM output driver, the Data  
Input  
(D)  
must  
not  
be  
applied  
until  
TWLQZ/TGHQZ/TSHQZ/TPLQZ after the output  
drive (Q) is put into a High-Z condition by  
NWE/NOE/NCS/NSL.
