General Description

The K4S280432C is 134,217,728 bits synchronous high data rate Dynamic RAM organized as 4 x 8,388,608 words by 4 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 ) -. 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 SD.
