128Mb: x4, x8, x16 DDR SDRAM

Functional Description

The DDR SDRAM uses a double data rate architecture to achieve high-speed operation.

The double data rate architecture is essentially a 2n-prefetch architecture with an inter-

face designed to transfer two data words per clock cycle at the I/O pins. A single read or

write access for the DDR SDRAM effectively consists of a single 2n-bit wide, one-clock-

cycle data transfer at the internal DRAM core and two corresponding

n-bit

wide, one-

half-clock-cycle data transfers at the I/O pins.

A bidirectional data strobe (DQS) is transmitted externally, along with data, for use in

data capture at the receiver. DQS is a strobe transmitted by the DDR SDRAM during

READs and by the memory controller during WRITEs. DQS is edge-aligned with data for

READs and center-aligned with data for WRITEs. The x16 offering has two data strobes,

one for the lower byte and one for the upper byte.

The DDR SDRAM operates from a differential clock (CK and CK#); the crossing of CK

going HIGH and CK# going LOW will be referred to as the positive edge of CK.

Commands (address and control signals) are registered at every positive edge of CK.

Input data is registered on both edges of DQS, and output data is referenced to both

edges of DQS, as well as to both edges of CK.

Read and write accesses to the DDR SDRAM are burst oriented; accesses start at a

selected location and continue for a programmed number of locations in a programmed

sequence. Accesses begin with the registration of an ACTIVE command, which may then

be followed by a READ or WRITE command. The address bits registered coincident with

the ACTIVE command are used to select the bank and row to be accessed. The address

bits registered coincident with the READ or WRITE command are used to select the bank

and the starting column location for the burst access.

The DDR SDRAM provides for programmable READ or WRITE burst lengths of 2, 4, or 8

locations. An AUTO PRECHARGE function may be enabled to provide a self-timed row

precharge that is initiated at the end of the burst access.

As with standard SDR SDRAMs, the pipelined, multibank architecture of DDR SDRAMs

allows for concurrent operation, thereby providing high effective bandwidth by hiding

row precharge and activation time.

An auto refresh mode is provided, along with a power-saving power-down mode. All

inputs are compatible with the JEDEC standard for SSTL_2. All full-drive option outputs

are SSTL_2, Class II compatible.

General Notes

• The functionality and the timing specifications discussed in this data sheet are for the

DLL-enabled mode of operation.

• Throughout the data sheet, the various figures and text refer to DQs as “DQ.” The DQ

term is to be interpreted as any and all DQ collectively, unless specifically stated

otherwise. Additionally, the x16 is divided into two bytes, the lower byte and upper

byte. For the lower byte (DQ0–DQ7) DM refers to LDM and DQS refers to LDQS. For

the upper byte (DQ8–DQ15) DM refers to UDM and DQS refers to UDQS.

• Complete functionality is described throughout the document and any page or

diagram may have been simplified to convey a topic and may not be inclusive of all

requirements.

• Any specific requirement takes precedence over a general statement.
