4M Late Write HSTL

The MCM63R736/818 is a 4M–bit synchronous late write fast static RAM

designed to provide high performance in secondary cache and ATM switch,

Telecom, and other high speed memory applications. The MCM63R818

(organized as 256K words by 18 bits), and the MCM63R736 (organized as 128K

words by 36 bits) are fabricated in Motorola’s high performance silicon gate

copper CMOS technology.

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

theRAM. AttherisingedgeofCK, alladdresses, writeenables, andsynchronous

selects are registered. An internal buffer and special logic enable the memory to

accept write data on the rising edge of CK, a cycle after address and control sig-

nals. Read data is also driven on the rising edge of CK.

The RAM uses HSTL inputs and outputs. The adjustable input trip–point (V

)

ref

and output voltage (V

) gives the system designer greater flexibility in

DDQ

optimizing system performance.

The synchronous write and byte enables allow writing to individual bytes or the

entire word.

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

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