GENERAL DESCRIPTION
FEATURES
The Samsung M466F0404BT2-L is a 4Mx64bits Dynamic
RAM high density memory module. The Samsung
M466F0404BT2-L consists of four CMOS 4Mx16bits DRAMs
in TSOP 400mil packages and a 2K EEPROM in 8-pin
TSSOP package mounted on a 144-pin glass-epoxy sub-
strate. A 0.1uF decoupling capacitor is mounted on the
printed circuit board for each DRAM. The M466F0404BT2-L is
a Small Out-line Dual in-line Memory Module and is intended
for mounting into 144 pin edge connector sockets.

NOTES
An initial pause of 200us is required after power-up followed
by any 8 RAS-only or CAS-before-RAS refresh cycles before
proper device operation is achieved.
1.
10. tASC³ 6ns, Assume tT=2.0ns
11. If RAS goes high before CAS high going, the open circuit
condition of the output is achieved by CAS high going. If CAS
goes high before RAS high going , the open circuit condition
of the output is achieved by RAS going.
2. Input voltage levels are Vih/Vil. VIH(min) and VIL(max) are
reference levels for measuring timing of input signals. Transi-
tion times are measured between VIH(min) and VIL(max) and
are assumed to be 5ns for all inputs.
12.
13.
14.
tASC is referenced to the earlier CAS falling edge and tCAH is
referenced to the later CAS falling edge.
3.
Measured with a load equivalent to 1 TTL loads and 100pF.
tCP is specified from the last CAS rising edge in the previous
cycle to the first CAS falling edge in the next cycle.
4. Operation within the tRCD(max) limit insures that tRAC(max)
can be met. tRCD(max) is specified as a reference point only.
If tRCD is greater than the specified tRCD(max) limit, then
access time is controlled exclusively by tCAC.
tCWD is referenced to the later CAS falling edge at word read-
modify-write cycle.
5.
Assumes that tRCD³ tRCD(max).
tCWL is specified from W falling edge to the earlier CAS rising
edge.
15.
16.
6. tWCS, tRWD, tCWD, tAWD and tCPWD are non-restrictive operat-
ing parameter. They are included in the data sheet as electri-
cal characteristics only. If tWCS³ tWCS(min), the cycle is an
early write cycle and the data out pin will remain high imped-
ance for the duration of the cycle. If tRWD³ tRWD(min),
tCWD³ tCWD(min), tAWD³ tAWD(min) and tCPWD³ tCPWD(min).
The cycle is a read-modify-write cycle and the data out will
contain data read from the selected cell. If neither of the
above sets of conditions is satisfied, the condition of data
out(at access time) is indeterminate.
tCSR is referenced to earlier CAS falling edge to the RAS fall-
ing edge.
17. tCHR is referenced to the later CAS rising from RAS falling
edge.
18.
19.
tDS, tDH is specified by the earlier CAS falling edge.
If tRASS³ 100us, then RAS precharge time must use tRPS
instead of tRP.
Either tRCH or tRRH must be satisfied for a read cycle.
7.
8.
20. For RAS-only refresh and burst CAS-before-RAS refresh
mode, 4096 cycles of burst refresh must be executed within
64ms before and after self refresh, in order to meet refresh
specification.
These parameters are referenced to the CAS leading edge in
early write cycles.
9.
Operation within the tRAD(max) limit insures that tRAC(max)
can be met. tRAD(max) is specified as reference point only. If
tRAD is greater than the specified tRAD(max) limit access time
is controlled by tAA.
21. For distributed CAS-before-RAS with 15.6us interval CAS-
before-RAS should be executed with in 15.6us immediately
before and after self refresh in order to meet refresh specifi-
cation.
