1-Gbit Double-Data-Rate-Two SDRAM
1.2
Description
The 1-Gbit DDR2 DRAM is a high-speed Double-Data-Rate-
Two CMOS Synchronous DRAM device containing
1,073,741,824 bits and internally configured as anoctal quad-
bank DRAM. The 1-Gb device is organized as either 16 Mbit
×8 I/O ×8 banks or 8 Mbit ×16 I/O ×8 banks chip. These
synchronous devices achieve high speed transfer rates
starting at 400 Mb/sec/pin for general applications.
latched at the cross point of differential clocks (CK rising and
CK falling). All I/Os are synchronized with a single ended
DQS or differential DQS-DQS pair in a source synchronous
fashion.
A 17 bit address bus for ×8 organised components and a
16 bit address bus for ×16 components is used to convey row,
column and bank address information in a RAS-CAS
multiplexing style.
The device is designed to comply with all DDR2 DRAM key
features:
The DDR2 device operates with a 1.8 V ± 0.1 V power
supply. An Auto-Refresh and Self-Refresh mode is provided
along with various power-saving power-down modes.
1. Posted CAS with additive latency,
2. Write latency = read latency - 1,
3. Normal and weak strength data-output driver,
4. Off-Chip Driver (OCD) impedance adjustment
5. On-Die Termination (ODT) function.
The functionality described and the timing specifications
included in this data sheet are for the DLL Enabled mode of
operation.
All of the control and address inputs are synchronized with a
pair of externally supplied differential clocks. Inputs are
The DDR2 SDRAM is available in PG-TFBGA package.
