MICRON MTA8ATF1G64HZ-3G2R1

MTA8ATF1G64HZ-3G2R1 is a high-speed DDR4 SDRAM module that uses DDR4 SDRAM devices with two or four internal memory bank groups. DDR4 SDRAM module utilizing 4- and 8-bit-wide DDR4 SDRAM devices has four internal bank groups consisting of four memory banks each, providing a total of 16 banks. 16-bit-wide DDR4 SDRAM device has two internal bank groups consisting of four memory banks each, providing a total of eight banks. DDR4 SDRAM modules benefit from the DDR4 SDRAM's use of an 8n-prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins. A single READ or WRITE operation for the DDR4 SDRAM effectively consists of a single 8n-bit-wide, four-clock data transfer at the internal DRAM core and eight corresponding n-bit-wide, one-half-clock-cycle data transfers at the I/O pins. DDR4 module uses two sets of differential signals: DQS-t and DQS-c to capture data and CK-t and CK-c to capture commands, addresses, and control signals.
