4M x 16 Bits x 4 Banks Synchronous DRAM

FEATURES

DESCRIPTION

The WED416S16030Ais 268,435,456 bits of synchronous

high data rate DRAM organized as 4 x 4,196,304 words x

16 bits. Synchronous design allows precise cycle control

with the use of system clock. I/O transactions are possible

on every clock cycle. Range of operating frequencies,

programmable burst lengths and programmable latencies

allow the same device to be useful for a variety of high

bandwidth, high performance memory system applica-

tions.

Single 3.3V power supply

Fully Synchronous to positive Clock Edge

Clock Frequency = 133, 125, and 100MH_Z

SDRAM CAS Latency = 2

Burst Operation

• Sequential or Interleave
