AS4C256M16D4 & AS4C512M8D4 4GB DDR4 SDRAMs

Alliance Memory AS4C256M16D4 and AS4C512M8D4 4GB DDR4 SDRMs offer low power consumption and fast data transfer rates in 96-ball and 78-ball FBGA packages. These 4GB high-speed SDRAMs reduce operating voltages from 1.5V to 1.2V (±0.06V) to increase battery life in portable electronics. The AS4C256M16D4 and AS4C512M8D4 4GB high-speed CMOS DDR4 SDRAMs come with easy-to-use refresh functions, including auto- or self-refresh. For improved efficiency and performance in desktop computers and servers, the 256Mb x 16-bit AS4C256M16D4 and 512Mb x 8-bit AS4C512M8D4 offer up to 16x memory banks. These 4GB SDRAMs are available in extended commercial (0°C to +95°C) and industrial (-40°C to +95°C) temperature ranges. The 4GB SDRAMs are ideal for portable electronics, desktop computers, and servers for industrial, medical, IoT, automotive, gaming, and consumer applications.
