General Description

ISSI's 2Gb DDR2 SDRAM uses a double-data-rate architecture to achieve high-speed operation.

The double-data rate architecture is essentially a 4n-prefetch architecture, with an interface designed to transfer two data words per clock cycle at the I/O balls.

Overview

IS43/46DR82560C IS43/46DR16128C 256Mx8, 128Mx16 DDR2 DRAM.

Key Features

  • Vdd = 1.8V ±0.1V, Vddq = 1.8V ±0.1V.
  • JEDEC standard 1.8V I/O (SSTL_18-compatible).
  • 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.
  • 8 internal banks for concurrent operation.
  • Programmable CAS latency (CL) 3, 4, 5, 6, and 7 supported.
  • Posted CAS and programmable additive latency (AL).
