Flow–Through BurstRAM

Synchronous Fast Static RAM

The MCM63F737K and MCM63F819K are 4M–bit synchronous fast static

RAMs designedtoprovideaburstable, highperformance, secondarycache. The

MCM63F737K (organized as 128K words by 36 bits) and the MCM63F819K

(organized as 256K words by 18 bits) 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).

TQ PACKAGE

TQFP

CASE 983A–01

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.

ZP PACKAGE

PBGA

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

addresses can be generated internally by the MCM63F737K and MCM63F819K

(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.

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.
