DDR4

Description

For increased efficiency and performance in 5G designs, desktop computers, and servers, Alliance Memory’s 4Gb, 8Gb, 16Gb DDR4 SDRAMs are available in clock speeds of up to 1600MHz for extremely high transfer rates to 3200Mbps/pin, while their reduced operating voltages to +1.2V increase battery life in portable electronics. Offered in with x8/x16 bus widths in 96-ball and 78-ball FBGA packages — and extended commercial and industrial temperature ranges — the DDR4 SDRAMs provide reliable drop-in, pin-for-pin compatible replacements for a number of similar solutions used in the industrial, medical, networking, IoT, automotive, gaming, and consumer markets.
