GENERAL DESCRIPTION
FOR 4M x 16Bit x 4 Bank gDDR2 SDRAM
The 256Mb gDDR2 SDRAM chip is organized as 4Mbit x 16 I/O x 4banks banks device. This synchronous device
achieve high speed graphic double-data-rate transfer rates of up to 1000Mb/sec/pin for general applications. The chip is
designed to comply with the following key gDDR2 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 cross point of differential clocks (CK rising and CK falling). All I/Os are synchronized with a pair of bidirec-
tional strobes (DQS and DQS) in a source synchronous fashion. A thirteen bit 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 address-
ing. The 256Mb gDDR2 devices operate with a single 1.8V ± 0.1V power supply and 1.8V ± 0.1V VDDQ.
The 256Mb gDDR2 devices are available in 84ball FBGAs(x16).
Note : The functionality described and the timing specifications included in this data sheet are for the DLL Enabled mode of
operation.
