Alliance Memory increases high speed SDRAMs line up with 8Gbit models
Alliance Memory has added 8Gbit devices to its high speed CMOS DDR4 SDRAMs.
According to Alliance Memory, the AS4C1G8D4 and AS4C512M16D4 deliver improved performance over previous-generation DDR3 SDRAMs. The AS4C1G8D4 and AS4C512M16D4 offer lower power consumption and faster data transfer rates in 78-ball and 96-ball FBGA packages, respectively.
Compared with DDR3 SDRAMs, the AS4C1G8D4 and AS4C512M16D4 SDRAMs reduce operating voltages from 1.65V to +1.2V (±0.06V) to increase battery life in portable electronics such as smartphones and tablets. For increased efficiency and performance in 5G designs, desktop computers, and servers, the 1Gb x 8-bit AS4C1G8D4 and the 512M x 16-bit AS4C512M16D4 offer up to 16 memory banks and deliver faster clock speeds of 1333MHz for extremely high transfer rates to 2666Mbps/pin.
The DDR4 SDRAMs have minimal die shrinks, which provides reliable drop-in, pin-for-pin-compatible replacements for many similar products, says Alliance. This eliminates the need for costly redesigns and part requalification.
The AS4C1G8D4 and AS4C512M16D4 are available in commercial (0 to +95 degrees C) and industrial (-40 to +95 degrees C) temperature ranges. The SDRAMs can be used in many applications in the industrial, networking, IoT, automotive, gaming, and consumer markets.
The AS4C1G8D4 and AS4C512M16D4 support sequential and interleave burst types with read or write burst lengths of BL8/BC4/BC4 or eight on the fly. An auto pre-charge function provides a self-timed row pre-charge initiated at the end of the burst sequence. Easy-to-use refresh functions include auto- or self-refresh. RoHS-compliant, the devices are lead- (Pb) and halogen-free.
Samples and production quantities of the 8Gbit DDR4 SDRAMs are available now, with lead times of eight to 10 weeks.
