SEMICONDUCTOR TECHNICAL DATA
MCM63D736
128K x 36 Bit Synchronous
Dual I/O, Dual Address SRAM
The MCM63D736 is a 4M–bit static random access memory, organized as
128K words of 36 bits. It features common data input and data output buffers and
incorporates input and output registers on–board with high speed SRAM.
The MCM63D736 allows the user to concurrently perform reads, writes, or
pass–throughcyclesincombinationonthetwodataports. Thetwoaddressports
(AX, AY) determine the read or write locations for their respective data ports
(DQX, DQY).
The synchronous design allows for precise cycle control with the use of an
external single clock (K). All signal pins except output enables (GX, GY) are
registered on the rising edge of clock (K).
TQ PACKAGE
176 LEAD TQFP
CASE 1101–01
The pass–through feature allows data to be passed from one port to the other,
in either direction. The PTX input must be asserted to pass data from port X to
port Y. The PTY will likewise pass data from port Y to port X. A pass–through
operation takes precedence over a read operation.
For the case when AX and AY are the same, certain protocols are followed. If
both ports are read, the reads occur normally. If one port is written and the other
is read, the read from the array will occur before the data is written. If both ports
are written, only the data on DQY will be written to the array.

This device contains circuitry to protect the
inputs against damage due to high static volt-

that normal precautions be taken to avoid
application of any voltage higher than maxi-
mum rated voltages to these high–impedance
