128K x 36 and 256K x 18 Bit

Flow–Through BurstRAM

Synchronous Fast Static RAM

The MCM63F737 and MCM63F819 are 4M–bit synchronous fast static RAMs

designed to provide a burstable, high performance, secondary cache for the

PowerPC and other high performance microprocessors. The MCM63F737 is

organized as 128K words of 36 bits each and the MCM63F819 is organized as

256K words of 18 bits each. These devices integrate 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), sleepmode(ZZ), andlinearburstorder(LBO)areclock(K)controlled

through positive–edge–triggered noninverting registers.

Bursts can be initiated with either ADSP or ADSC input pins. Subsequent burst

addresses can be generated internally by the MCM63F737 and MCM63F819

(burstsequenceoperatesinlinearorinterleavedmodedependentuponthestate

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.

CASE 999–02

Synchronous byte write (SBx), synchronous global write (SGW), and

synchronous write enable (SW) are provided to allow writes to either individual

bytes or to all bytes. The bytes are designated as “a”, “b”, etc. 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 MCM63F737 and MCM63F819 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.
