Low-Power DDR2 SDRAM

Alliance Memory Low-Power DDR2 SDRAM are high-speed CMOS and dynamic-access memory internally configured as an 8-bank device. These DDR2 SDRAM feature 4-bit pre-fetch DDR architecture, programmable READ and WRITE latencies, auto Temperature Compensated Self Refresh (TCSR), and clock stop capability. The DDR2 SDRAM reduces the number of input pins in the system by using a double data rate architecture on the Command/Address (CA) bus. This CA bus transmits address, command, and bank information. These DDR2 SDRAM can achieve high-speed operation by using a double data rate architecture on the DQ (bidirectional/differential data bus) pins.
