The H2A401G0866B is a 1G bits DDR3 SDRAM, organized as 16,777,216 words × 8 banks × 8 bits. This device achieves high speed transfer rates up to 1600 Mb/sec/pin (DDR3-1600) for various applications.
The H2A401G0866B is designed to comply with the following key DDR3 SDRAM features such as posted /CAS, programmable /CAS Write Latency (CWL), ZQ calibration, on die termination and asynchronous reset. 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 differential DQS-DQS# pair in a source synchronous fashion.
