kvr1066d3s8s7/2g 2gb 1rx8 256m x 64-bit pc3-1066 cl7 204-pin sodimm description this document describes valueram's 256m x 64-bit (2gb) ddr3-1066 cl7 sdram (synchronous dram), 1rx8 memory module, based on eight 256m x 8-bit ddr3-1066 fbga compo- nents. the spd is programmed to jedec standard latency ddr3-1066 timing of 7-7-7. this 204-pin sodimm uses gold contact fingers. the electrical and mechanical specifications are as follows: features ? jedec standard 1.5v (1.425v ~1.575v) power supply ? vddq = 1.5v (1.425v ~ 1.575v) ? 533mhz fck for 1066mb/sec/pin ? 8 independent internal bank ? programmable cas latency: 9, 8, 7, 6 ? programmable additive latency: 0, cl - 2, or cl - 1 clock ? programmable cas write latency(cwl) = 6 (ddr3-1066) ? 8-bit pre-fetch ? burst length: 8 (interleave without any limit, sequential with starting address ?000? only), 4 with tccd = 4 which does not allow seamless read or write [either on the fly using a12 or mrs] ? bi-directional differential data strobe ? internal(self) calibration: internal self calibration through zq pin (rzq : 240 ohm 1%) ? on die termination using odt pin ? average refresh period 7.8us at lower than tcase 85c, 3.9us at 85c < tcase < 95c ? asynchronous reset ? pcb: height 1.18?
