128K x 36 Bit Flow–Through BurstRAM Synchronous Fast Static RAM
The MCM69F735 is a 4M bit synchronous fast static RAM designed to provide a burstable, high performance, secondary cache for the PowerPC and other high performance microprocessors. It is organized as 128K words of 36 bits each. This device integrates input registers, a 2–bit address counter, and high speed SRAM onto a single monolithic circuit for reduced parts count in cache data RAM applications. Synchronous design allows precise cycle control with the use of an external clock (K).
Addresses (SA), data inputs (DQx), and all control signals except output enable (G edge–triggered noninverting registers.
addresses can be generated internally by the MCM69F735 (burst sequence operates in linear or interleaved mode dependent upon the state of LBO controlled by the burst address advance (ADV
clock (K) input. This feature eliminates complex off–chip write pulse generation and provides increased timing flexibility for incoming signals.
nous write enable (SW to all bytes. The four bytes are designated as “a”, “b”, “c”, and “d”. SBa DQa, SBb writes SBx or if all SBx
from the memory array . operate on a 3.3 V or 2.5 V power supply . All inputs and outputs are JEDEC stan-
dard JESD8–5 compatible.

and SW are asserted.
For read cycles, a flow–through SRAM allows output data to simply flow freely

APPLICATION INFORMATION
STOP CLOCK OPERATION
In the stop clock mode of operation, the SRAM will hold all state and data values even though the clock is not running (full static operation). The SRAM design allows the clock to start with ADSP
and ADSC, and stops the clock after the last
write data is latched, or the last read data is driven out.
When starting and stopping the clock, the AC clock timing and parametrics must be strictly maintained. For example, clock pulse width and edge rates must be guaranteed when

starting and stopping the clocks.
To achieve the lowest power operation for all three stop
clock modes, stop read, stop write, and stop deselect:
1. Force the clock to a low state.
2. Force the control signals to an inactive state (this guar­antees any potential source of noise on the clock input will not start an unplanned on activity).
3. Force the address inputs to a low state (VIL), preferably < 0.2 V.

buffers. For lowest power operation, all data and address lines should be held in a low (VIL) state and control lines held in an inactive state.

NON–BURST SYNCHRONOUS OPERATION
Although this BurstRAM has been designed for PowerPC– based 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 MCM69F735. The burst counter
