GENERAL DESCRIPTION

The HMS3224M3/Z3 is a high-speed static random access memory (SRAM) module containing 32,768 words

organized in a x24-bit configuration. The module consists of three 32K x 8 SRAMs mounted on a 56-pin, single-

sided, FR4-printed circuit board.

Writing to the device is accomplished when the chip enable (/CE) and write enable(/WE) inputs are both LOW.

Data on the input/output pins (DQ0 through DQ23) of the device is written into the memory location specified

on the address pins (A0 through A14).

Reading the device is accomplished by taking the chip enable (/CE) and output enable(/OE) LOW while write

enable(/WE) remains HIGH. Under these conditions, the contents of the memory location specified on the address

pins will appear on the input/output pins.

The input/output pins remains in a high-impedance state unless the module is selected, outputs are enabled, and

write enable is HIGH.
