General Description

The K4S640832F is 67,108,864 bits synchronous high data rate Dynamic RAM organized as 4 x 2,097,152 words by 8 bits, fabricated with SAMSUNG′s high performance CMOS technology.

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 length and programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.

Key Features

  • JEDEC standard 3.3V power supply LVTTL compatible with multiplexed address Four banks operation MRS cycle with address key programs -. CAS latency (2 & 3) -. Burst length (1, 2, 4, 8 & Full page) -. Burst type (Sequential & Interleave) All inputs are sampled at the positive going edge of the system clock Burst read single-bit write operation DQM for masking Auto & self refresh 64ms refresh period (4K Cycle) CMOS SDRAM.
