The 512Mb DDR2 SDRAM is organized as a 32Mbit x 4
I/Os x 4 banks, 16Mbit x 8 I/Os x 4banks or 8Mbit x 16 I/Os
x 4 banks device. This synchronous device achieves high
speed
533Mb/sec/pin (DDR2-533) 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 Termina-
tion.
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 synchro-
nous fashion. The address bus is used to convey row, col-
umn, and bank address information in a RAS/CAS
multiplexing style. For example, 512Mb(x4) device receive
14/11/2 addressing.
The 512Mb DDR2 device operates with a single
1.8V ± 0.1V power supply and 1.8V ± 0.1V VDDQ.
The
FBGAs(x4/x8) and in 84ball FBGAs(x16).
Note: The functionality described and the timing specifica-
tions included in this data sheet are for the DLL Enabled
mode of operation.
