Description

ISSI's 256Mb DDR2 SDRAM uses a double-data-rate architecture to achieve high-speed operation.

Key Features

  • Double data rate interface: two data transfers per clock cycle
  • Differential data strobe (DQS, DQS)
  • 4-bit prefetch architecture
  • On chip DLL to align DQ and DQS transitions with CK
  • 4 internal banks for concurrent operation
  • Programmable CAS latency (CL) 3, 4, 5, and 6 supported
  • Posted CAS and programmable additive latency (AL) 0, 1, 2, 3, 4, and 5 supported
  • WRITE latency = READ latency - 1 tCK
  • Adjustable data-output drive strength, full and reduced strength options
  • On-die termination (ODT)
