DDR2 SDRAM Manufacturer
1Gb (16Mx8Banks×8) DDR2 SDRAM
This synchronous device achieves high speed double-data-rate transfer rates of up to 1066 Mb/sec/pin (DDR2-1066) for general applications. The chip is designed to comply with the following key DDR2 SDRAM features:
- posted CAS with additive latency,
- write latency = read latency -1,
- Off-Chip Driver (OCD) impedance adjustment and On Die Termination
- normal and weak strength data output driver.
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 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 DDR2 devices operate with a single power supply: 1.8V ± 0.1V VDD and VDDQ.
Available package: TFBGA-60Ball.
