IS43DR16640D - 64Mx16 DDR2 DRAM

This page provides the datasheet information for the IS43DR16640D, a member of the IS46DR81280D 64Mx16 DDR2 DRAM family.

Datasheet Summary

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.
