Advance Information

MCM69Q618

64K x 18 Bit Synchronous

Separate I/O Fast SRAM

The Motorola MCM69Q618 is a 1 Megabit static random access memory, organized

as 64K words of 18 bits. It features separate data input and data output buffers and

incorporates input and output registers on board with high speed SRAM.

The MCM69Q618 allows the user to perform transparent write and data pass

through. Two data bus ports are provided – a data input (D) and a data output (Q) port.

The synchronous design allows for precise cycle control with the use of an external

single clock (K). Address port, data input (D0 – D17), data output (Q0 – Q17), write en-

able (W), chip enables (E1, E2), and pass–through enable (PT) are registered on the

rising edge of clock (K).

Any given cycle operates on only one address. However, for any cycle, reads and

writes can be intermixed. Thus, one can perform a read, a write, or a combination read/

write during any one cycle. For a combination read/write, the contents of the array are

read before the new data is written.

By using the pass–through function, the output port Q can be made to reflect either

the contents of the array or the data presented to the input port D. For read/write or a

read cycle with G low, the Q port will output the contents of the array. However, if PT

is asserted, the Q port will instead output the data presented at the D input port.
