It is internally configured as an eight bank Backward compatible to V & V = 1.5V 0.075V DD DDQ DRAM. Operating temperature: -40~95 C (TC) The 4Gb chip is organized as 32Mbit x 16 I/Os x 8 Supports JEDEC clock jitter specification bank devices. These synchronous devices achieve Fully synchronous operation high speed double-data-rate transfer rates of up to Fast clock rate: 800 MHz 1600 Mb/sec/pin for general applications. The chip is designed to comply with all key DDR3L Differential Clock, CK & CK DRAM key features and all of the control and address Bidirectional differential data strobe inputs are synchronized with a pair of externally - DQS & DQS supplied differential clocks. Inputs are latched at the 8 internal banks for concurrent operation cross point of differential clocks (CK rising and CK 8n-bit prefetch architecture falling). All I/Os are synchronized with differential DQS Pipelined internal architecture pair in a source synchronous fashion. Precharge & active power down These devices operate with a single 1.35V -0.067V Programmable Mode & Extended Mode registers /+0.1V power supply and are available in BGA packages.
