128K x 32 Bit Flow–Through
BurstRAM Synchronous
Fast Static RAM
The MCM63F733A and SCM63F733A are 4M–bit synchronous fast static
RAMs designed to provide a burstable, high performance, secondary cache for
the PowerPC and other high performance microprocessors. They are orga-
nized as 128K words of 32 bits each, fabricated with high performance silicon
gate CMOS technology. This device integrates input registers, a 2–bit address
counter, andhighspeedSRAMontoasinglemonolithic circuitforreducedparts
count in cache data RAM applications. Synchronous design allows precise
cycle control with the use of an external clock (K). CMOS circuitry reduces the
overall power consumption of the integrated functions for greater reliability.
Addresses (SA), data inputs (DQx), and all control signals except output
enable (G) and Linear Burst Order (LBO) are clock (K) controlled through
positive–edge–triggered noninverting registers.

TQFP
CASE 983A–01
Bursts can be initiated with either ADSP or ADSC input pins. Subsequent burst
addresses can be generated internally by the MCM63F733A and SCM63F733A
(burst sequence operates in linear or interleaved mode dependent upon state of
LBO) and controlled by the burst address advance (ADV) input pin.
Write cycles are internally self–timed and are initiated by the rising edge of the
clock (K) input. This feature eliminates complex off–chip write pulse generation
and provides increased timing flexibility for incoming signals.
Synchronous byte write (SBx), synchronous global write (SGW), and synchro-
nous write enable (SW) are provided to allow writes to either individual bytes or
to all bytes. The four bytes are designated as “a”, “b”, “c”, and “d”. SBa controls
DQa, SBb controls DQb, etc. Individual bytes are written if the selected byte
writes SBx are asserted with SW. All bytes are written if either SGW is asserted
or if all SBx and SW are asserted.
For read cycles, a flow–through SRAM allows output data to simply flow freely
from the memory array.
The MCM63F733A and SCM63F733A operate from a 3.3 V core power supply
and all outputs operate on a 2.5 V or 3.3 V power supply. All inputs and outputs
are JEDEC Standard JESD8–5 compatible.

Sleep Mode: This active high asynchronous signal places the RAM into

low power mode until it is commanded to READ or WRITE. Data

1. X = Don’t Care. 1 = logic high. 0 = logic low.
2. Write is defined as either 1) any SBx and SW low, or 2) SGW is low.
3. G is an asynchronous signal and is not sampled by the clock K. G drives the bus immediately (t
) following G going low.
GLQX
4. On write cycles that follow read cycles, G must be negated prior to the start of the write cycle to ensure proper write data setup times.
G must also remain negated at the completion of the write cycle to ensure proper write data hold times.

NOTES:
1. Write is defined as either any SBx and SW low or SGW is low. Chip Enable is defined as SE1 low, SE2 high, and SE3 low whenever ADSP
or ADSC is asserted.
2. All read and write cycle timings are referenced from K or G.
3. G is a don’t care after write cycle begins. To prevent bus contention, G should be negated prior to start of write cycle.
4. In order to reduce test correlation issues and to reduce the effects of application specific input edge rate variations on correlation between
data sheet parameters and actual system performance, FSRAM AC parametric specifications are always specified at V
/2. In some
DDQ
designexercises, it is desirable to evaluate timing using other reference levels. Since the maximum test input edge rate is known and is given
in the AC Test Conditions section of the data sheet as 1 V/ns, one can easily interpolate timing values to other reference levels.
5. This parameter is sampled and not 100% tested.
6. Measured at ± 200 mV from steady state.

APPLICATION INFORMATION
SLEEP MODE

rent (I ). All inputs are allowed to toggle — the RAM will not
ZZ
A sleep mode feature, the ZZ pin, has been implemented
on the MCM63F733A and SCM63F733A. It allows the sys-
tem designer to place the RAM in the lowest possible power
condition by asserting ZZ. The sleep mode timing diagram
shows the different modes of operation: Normal Operation,
No READ/WRITE Allowed, and Sleep Mode. Each mode has
its own set of constraints and conditions that are allowed.
Normal Operation: All inputs must meet setup and hold
be selected and perform any reads or writes. However, if
inputs toggle, the I (max) specification will not be met.
ZZ
NON–BURST SYNCHRONOUS OPERATION
Although this BurstRAM has been designed for PowerPC
— and other high end MPU–based systems, these SRAMs
can be used in other high speed L2 cache or memory
applications that do not require the burst address feature.
Most L2 caches designed with a synchronous interface can
make use of the MCM63F733A and SCM63F733A. The
burst counter feature of the BurstRAM can be disabled, and
the SRAM can be configured to act upon a continuous
stream of addresses. See Figure 5.

covering from sleep. Clock (K) must also meet cycle, high,
and low times during these periods. Two cycles prior to sleep,
initiation of either a read or write operation is not allowed.
No READ/WRITE: During the period of time just prior to
sleep and during recovery from sleep, the assertion of either
ADSC, ADSP, or any write signal is not allowed. If a write
operation occurs during these periods, the memory array
may be corrupted. Validity of data out from the RAM can not
be guaranteed immediately after ZZ is asserted (prior to
being in sleep).
