4194304-BIT (524288-WORD BY 8-BIT) CMOS STATIC RAM
DESCRIPTION
The M5M5V4R08J is a family of 524288-word by 8-bit static RAMs, fabricated with the high performance CMOS silicon gate process and designed for high speed application. The M5M5V4R08J is offered in a 36-pin plastic small outline J-lead package(SOJ). These device operate on a single 3.3V supply, and are directly TTL compatible. They include a power down feature as well.

FUNCTION
The operation mode of the M5M5V4R08J is determined by a combination of the device control inputs S, W and OE. Each mode is summarized in the function table. A write cycle is executed whenever the low level W overlaps with the low level S. The address must be set-up before the write cycle and must be stable during the entire cycle. The data is latched into a cell on the trailing edge of W or S, whichever occurs first, requiring the set-up and hold time relative to these edge to be maintained. The output enable input OE directly controls the output stage. Setting the OE at a high level, the output stage is in a high impedance state, and the data bus contention problem in the write cycle is eliminated. A read cycle is excuted by setting W at a high level and OE at a low level while S are in an active state (S=L). When setting S at high level, the chip is in a non-selectable mode in which both reading and writing are disable. In this mode, the output stage is in a high-impedance state, allowing OR-tie with other chips and memory expansion by S. Signal-S controls the power-down feature. When S goes high, power dissapation is reduced extremely. The access time from S is equivalent to the address access time.
