ALLIANCE MEMORY AS4C512M8D3LC-12BCN DRAM, DDR3, 4 Gbit, 512M x 8bit, 800 MHz, FBGA, 78 Pins

AS4C512M8D3LC-12BCN is a 512M x 8-bit DDR3L synchronous DRAM (SDRAM). The 4Gb double-data-rate-3 (DDR3L) DRAMs is a double data rate architecture to achieve high-speed operation. It is internally configured as an eight-bank DRAM. The 4Gb chip is organized as 64Mbit x 8 I/Os x 8 bank devices. This synchronous device achieves high-speed double-data-rate transfer rates of up to 1600Mb/sec/pin for general applications. The chip is designed to comply with all key DDR3L DRAM key features and 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 differential DQS pairs in a source-synchronous fashion.
