Product Preview

8MB Double Data Rate HSTL I/O

Fast SRAM

The MCM64E918/MCM64E836 are 8M–bit pipelined burst synchronous late

writefaststaticRAMsdesignedtoprovideveryhighdatabandwidthinsecondary

cache applications. The MCM64E918 (organized as 512K words by 18 bits wide)

and the MCM64E836 (organized as 256K words by 36 bits wide) are fabricated

in Motorola’s high performance silicon gate MOS technology.

The differential clock (CK) inputs control the timing of read/write operations of

the RAM. At the rising edge of CK, all addresses and burst control inputs are

registered. An internal buffer and special logic enables the memory to accept

write data on the rising or rising and falling edges of the clock, a cycle following

address and control signals. Read data is driven on the rising or rising and falling

edges of the CK clock and is referenced to echo clock (CQ and CQ) outputs.

The MCM64E918/MCM64E836 have HSTL inputs and outputs. The adjust-

the system designer greater flexibility in optimizing system performance.

The impedance of the output buffers is programmable, allowing the outputs to

match the impedance of the circuit traces, which reduces signal reflections.
