The 256Mb DDR2 SDRAM is organized as a 4Mbit x 16 I/Os x 4
banks device. This synchronous device achieves high speed dou-
ble-data-rate transfer rates of up to 800Mb/sec/pin (DDR2-800) for
general applications.
The chip is designed to comply with the following key DDR2
SDRAM features such as posted CAS with additive latency, write
latency = read latency -1, Off-Chip Driver(OCD) impedance
adjustment and On Die Termination.
All of the control and address inputs are synchronized with a pair
of externally supplied differential clocks. Inputs are latched at the
crosspoint of differential clocks (CK rising and CK falling). All I/Os
are synchronized with a pair of bidirectional strobes (DQS and
DQS) in a source synchronous fashion. The address bus is used
to convey row, column, and bank address information in a RAS/
CAS multiplexing style. For example, 256Mb(x16) device receive
13/9/2 addressing.
The 256Mb DDR2 device operates with a single 1.8V ± 0.1V
power supply and 1.8V ± 0.1V VDDQ.
The 256Mb DDR2 device is available in 84ball FBGAs(x16).
