Description
All of the control and address inputs are synchronized with a
pair of externally supplied differential clocks. Inputs are
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 18 bit address bus for
×4
and
×8
organised components is
used to convey row, column and bank address information in
a RAS-CAS multiplexing style.
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.
The functionality described and the timing specifications
included in this data sheet are for the DLL Enabled mode of
operation.
The DDR2 SDRAM is available in TFBGA package.
The 2-Gbit DDR2 DRAM is a high-speed Double-Data-Rate-
Two CMOS Synchronous DRAM device containing 2,147,
483, 648 bits and internally configured as an octal bank
DRAM. The 2-Gbit device is organized as 64 Mbit
×4
I/O
×8
banks or 32 Mbit
×8
I/O
×8
banks chip.
These synchronous devices achieve high speed transfer
rates starting at 400 Mb/sec/pin for general applications. See
Table 1
for performance figures.
The device is designed to comply with all DDR2 DRAM key
features:
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.
