GENERAL DESCRIPTION  
The HMS1M32M8A is a high-speed static random access memory (SRAM) module containing 1,048,576 words  
organized in a x32-bit configuration. The module consists of eight 1M x 4 SRAMs mounted on a 64-pin, double-  
sided, FR4-printed circuit board.  
Four chip enable inputs, (/CE1, /CE2, /CE3 and /CE4) are used to enable the module’s 4 bytes independently.  
Output enable (/OE) and write enable(/WE) can set the memory input and output.  
Data is written into the SRAM memory when write enable (/WE) and chip enable (/CE) inputs are both LOW.  
Reading is accomplished when /WE remains HIGH and /CE and output enable (/OE) are LOW.  
For reliability, this SRAM module is designed as multiple power and ground pin. All module components may be  
powered from a single +5V DC power supply and all inputs and outputs are fully TTL-compatible.
