1-Gbit Double-Data-Rate-Two SDRAM

1Overview

This chapter gives an overview of the 1-Gbit Double-Data-Rate-Two SDRAM product family and describes its main

characteristics.

1.1

Features

The 1-Gbit Double-data-Rate SDRAM offers the following key features:

• 1.8 V

± 0.1 V Power Supply

1.8 V

± 0.1 V (SSTL_18) compatible I/O

• DRAM organizations with 4, 8 and 16 data in/outputs

• Double Data Rate architecture: two data transfers per

clock cycle four internal banks for concurrent operation

• Programmable CAS Latency: 3, 4, 5 and 6

• Programmable Burst Length: 4 and 8

• Differential clock inputs (CK and CK)

• Bi-directional, differential data strobes (DQS and DQS) are

transmitted / received with data. Edge aligned with read

data and center-aligned with write data

• DLL aligns DQ and DQS transitions with clock

•DQS can be disabled for single-ended data strobe

operation

• Commands entered on each positive clock edge, data and

data mask are referenced to both edges of DQS

• Data masks (DM) for write data

• Posted CAS by programmable additive latency for better

command and data bus efficiency

• Off-Chip-Driver impedance adjustment (OCD) and On-

Die-Termination (ODT) for better signal quality

• Auto-Precharge operation for read and write bursts

• Auto-Refresh, Self-Refresh and power saving Power-

Down modes

• Average Refresh Period 7.8

µs at a T

CASE lower than

85 °C, 3.9

µs between 85 °C and 95 °C

• Programmable self refresh rate via EMRS2 setting

• Programmable partial array refresh via EMRS2 settings

• DCC enabling via EMRS2 setting

• Full and reduced Strength Data-Output Drivers

• 1K page size for

×4 & ×8, 2K page size for ×16

• Package: P(G)-TFBGA-68 , P(G)-TFBGA-84

and PG-TFBGA-92

• RoHS Compliant Products1)

• All Speed grades faster than DDR2–400 comply with

DDR2–400 timing specifications when run at a clock rate

of 200 MHz.
