• JEDEC standard 1.35V(1.28V~1.45V) & 1.5V(1.425V~1.575V)
•VDDQ = 1.35V(1.28V~1.45V) & 1.5V(1.425V~1.575V)
• 400 MHz fCK for 800Mb/sec/pin, 533MHz fCK for 1066Mb/sec/pin,
667MHz fCK for 1333Mb/sec/pin, 800MHz fCK for 1600Mb/sec/pin
• 8 Banks
• Programmable CAS Latency(posted CAS): 5,6,7,8,9,10,11

• All of Lead-Free products are compliant for RoHS
• All of products are Halogen-free
The 2Gb DDR3 SDRAM D-die is organized as a 64Mbit x 4 I/Os x 8banks,
32Mbit x 8 I/Os x 8banks device. This synchronous device achieves high
speed double-data-rate transfer rates of up to 1600Mb/sec/pin (DDR3-
1600) for general applications.
The chip is designed to comply with the following key DDR3 SDRAM fea-
tures such as posted CAS, Programmable CWL, Internal (Self) Calibration,
On Die Termination using ODT pin and Asynchronous Reset .
All of the control and address inputs are synchronized with a pair of exter-
nally supplied differential clocks. Inputs are latched at the crosspoint of dif-
ferential clocks (CK rising and CK falling). All I/Os are synchronized with a
pair of bidirectional strobes (DQS and DQS) in a source synchronous fash-
ion. The address bus is used to convey row, column, and bank address
information in a RAS/CAS multiplexing style. The DDR3 device operates
with a single 1.35V(1.28V~1.45V) or 1.5V(1.425V~1.575V) power supply
and 1.35V(1.28V~1.45V) or 1.5V(1.425V~1.575V).
The 2Gb DDR3 D-die device is available in 78ball FBGAs(x4/x8)
NOTE : 1. This data sheet is an abstract of full DDR3 specification and does not cover the common features which are described in “DDR3 SDRAM Device Operation & Timing
Diagram”.
2. The functionality described and the timing specifications included in this data sheet are for the DLL Enabled mode of operation.
