DDR3 SDRAM Manufacturer

DDR3 SDRAM is being widely used today by businesses as a way to make DDR3 SDRAM can do a variety of other functions depending on what specific needs the business requires. To ensure that the requirements of this policy are met, Axeme - Hwaling Technology Co., Ltd. will keep providing and maintaining safe and healthy working conditions, equipment and systems of work, together with adequate information, instruction, training and supervision for all employees.

H2A401G1666A

1Gb (8Mx8Banksx16) DDR3 SDRAM

The H2A401G1666A is a high speed Double Date Rate 3 (DDR3) Synchronous DRAM fabricated with ultra high performance CMOS process containing 1G bits which organized as 8Mbits x 8 banks by 16 bits.
This synchronous device achieves high speed double-data-rate transfer rates of up to 1600 Mb/sec/pin (DDR3-1600) 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. The 1Gb DDR3 devices operates with a single power supply: 1.5V ± 0.075V VDD and VDDQ. Available package: FBGA-96Ball (with 0.8mm - 0.8mm ball pitch)
Features :
