64K x 16 Bit 3.3 V Asynchronous
Fast Static RAM
The MCM6323A is a 1,048,576 bit static random access memory organized
as 65,536 words of 16 bits. Static design eliminates the need for external clocks
or timing strobes; CMOS circuitry reduces power consumption and provides for
greater reliability.
The MCM6323A is equipped with chip enable (E), write enable (W), and output
enable (G) pins, allowing for greater system flexibility and eliminating bus contention
problems. Separate byte enable controls (LB and UB) allow individual bytes to be
written and read. LB controls the 8 DQa bits, while UB controls the 8 DQb bits.
The MCM6323A is available in a 400 mil small–outline J–leaded (SOJ) pack-
age and a 44–lead TSOP Type II package in copper leadframe for optimum
printed circuit board (PCB) reliability.
