New Product Introduction

Alliance Memory AS4C256M16D4 and AS4C512M8D4

Alliance Memory has expanded its product offering with a new line of high-speed CMOS DDR4 SDRAMs - AS4C256M16D4 and AS4C512M8D4

Compared to DDR3 SDRAMs, Alliance Memory’s new 4Gb DDR4 SDRAMs reduce operating voltages from 1.5V to +1.2V (±0.06V) to increase battery life in portable electronics such as notebook computers, smartphones, and tablets. 

For increased efficiency and performance in desktop computers and servers, the 256Mb x 16-bit AS4C256M16D4 and 512M x 8-bit AS4C512M8D4 offer up to 16 memory banks and deliver faster clock speeds to 1333MHz for extremely high transfer rates of 2400Mbps/pin (1200MHz) and 2666Mbps/pin (1333MHz).

With minimal die shrinks, the DDR4 SDRAMs provide reliable drop-in, pin-for-pin-compatible replacements for numerous similar solutions — eliminating the need for costly redesigns and part requalification.
