PD4382323, 4382363
8M-BIT CMOS SYNCHRONOUS FAST SRAM
PIPELINED OPERATION
DOUBLE CYCLE DESELECT
Description
The
碌
PD4382323 is a 262,144-word by 32-bit and the
碌
PD4382363 is a 262,144-word by 36-bit synchronous static RAM
fabricated with advanced CMOS technology using N-channel four-transistor memory cell.
The
碌
PD4382323 and
碌
PD4382363 integrates unique synchronous peripheral circuitry, 2-bit burst counter and output
buffer as well as SRAM core. All input registers are controlled by a positive edge of the single clock input (CLK).
The
碌
PD4382323 and
碌
PD4382363 are suitable for applications which require synchronous operation, high speed, low
voltage, high density and wide bit configuration, such as cache and buffer memory.
ZZ has to be set LOW at the normal operation. When ZZ is set HIGH, the SRAM enters Power Down State (鈥淪leep鈥?. In
the 鈥淪leep鈥?state, the SRAM internal state is preserved. When ZZ is set LOW again, the SRAM resumes normal operation.
The
碌
PD4382323 and
碌
PD4382363 are packaged in 100-pin plastic LQFP with a 1.4 mm package thickness for high
density and low capacitive loading.
