H2A404G0866C

4Gb (64Mx8Banks×8) DDR3 SDRAM

The H2A404G0866C is a high speed Double Date Rate 3 (DDR3) low voltage Synchronous DRAM fabricated with ultra high performance CMOS process containing 4,294,967,296 bits which organized as 64Mbits x 8 banks by 8 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 with bank-grouping.

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 4Gb DDR3 devices operates with a single power supply: 1.5V±0.075V VDD and VDDQ.
Available package: FBGA-78Ball (with 0.8mm x 0.8mm ball pitch)
Features :

  • JEDEC Standard VDD/VDDQ = 1.5V±0.075V
  • All inputs and outputs are compatible with SSTL_15 interface.

  • Bi-directional Differential Data Strobe (DQS).
  • Data inputs on DQS centers when write.
  • Data outputs on DQS, /DQS edges when read.
  • On chip DLL align DQ, DQS and /DQS transition with CK transition.
  • DM mask write data-in at the both rising and falling edges of the data strobe.
  • Sequential & Interleaved Burst type available both for 8 & 4 with BC.
  • Multi Purpose Register (MPR) for pre-defined pattern read out
  • On Die Termination (ODT) options: Synchronous ODT, Dynamic ODT, and Asynchronous ODT
