DDR3 SDRAM

Product Name : 4Gb (32Mx8Banksx16) DDR3 SDRAM

Item No. : N4D04G16E

Description

The N4D04G16E is a high speed Double Date Rate 3 (DDR3) Synchronous DRAM fabricated with ultra high performance CMOS process containing 4G bits which organized as 32Mbits x 8 banks by 16 bits.

This synchronous device achieves high speed double-data-rate transfer rates of up to 1866 Mb/sec/pin (DDR3-1866) for general applications.

The chip is designed to comply with the following key DDR3 SDRAM features: (1) posted CAS with additive latency, (2) write latency = read latency -1, (3) On Die Termination (4) programmable driver strength data,(5) seamless BL4 access.

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 bidirectional differential data 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 and /CAS multiplexing style.
