IS46DR81280DL - 128Mx8 DDR2 DRAM

Download the IS46DR81280DL datasheet PDF. This datasheet also covers the IS46DR81280D variant, as both devices belong to the same 128mx8 ddr2 dram family and are provided as variant models within a single manufacturer datasheet.

Description

ISSI's 1Gb 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.

Features

  • Standard Voltage: Vdd and Vddq = 1.8V ±0.1V.
  • Low Voltage (L): Vdd and Vddq = 1.5V ±0.075V.
  • SSTL_18-compatible for Standard Voltage.
  • SSTL_15-compatible for Low Voltage.
  • 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 CA.
