Kingston DDR3 SO RAM 2GB PC1333

This document describes Value RAM's 256M x 64-bit 2GB (2048MB) DDR3-1333 CL9 SDRAM (Synchronous DRAM) Memory Module based on sixteen 128M x 8-bit DDR3-1333 FBGA components. The SPD is programmed to JEDEC Standard latency 1333Mhz timing of 9-9-9 at 1.5V. This 240-pin DIMM uses gold contact fingers and requires +1.5V.

• JEDEC standard 1.5V ? 0.075V Power Supply
• VDDQ = 1.5V ? 0.075V
• 667MHz fCK for 1333Mb/sec/pin
• 8 independent internal bank
• Programmable CAS Latency: 5,6,7,8,9,10
• Posted CAS
• Programmable Additive Latency: 0, CL - 2, or CL - 1 clock
• Programmable CAS Write Latency(CWL) = 9(DDR3-1333)
• 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 then TCASE 85?C, 3.9us at 85?C < TCASE . 95?C
• Asynchronous Reset
• 1066Mbps CL7 doesn?t have backward compatibility with 800Mbps CL5
• PCB : Height 1.180? (30.00mm), double sided component

• CL(IDD) 9 cycles
• Row Cycle Time (tRCmin) 49.5ns (min.)
• Refresh to Active/Refresh Command Time (tRFCmin) 90ns
• Row Active Time (tRASmin) 36ns (min.)
• Power TBD W (operating)
• UL Rating 94 V - 0
• Operating Temperature 0o C to 85o C
• Storage Temperature -55o C to +100o C
