SAN CARLOS, Calif. — April 12, 2017 — ALLIANCE Memory introduced a line of high-speed CMOS mobile low-power DDR2 SDRAMs(Mobile LPDDR2 SDRAMs) with densities of 1Gb, 2Gb, and 4Gb in the 134-ball FBGA package. The devices offer a variety of power-saving features, including 1.2 V/1.8 V operating voltages, to extend battery life in portable electronics, while their high density enables ultra-slim designs.

The LPDDR2 SDRAMs provide reliable drop-in, pin-to-pin compatible replacements for a number of similar solutions in ultra-low-voltage cores and I/O power supplies for mobile devices such as smartphones and tablets. For these products, the ICs feature auto temperature-compensated self-refresh (TCSR) to minimize power consumption at lower ambient temperatures. In addition, their partial-array self-refresh (PASR) feature reduces power by only refreshing critical data, while a deep power down (DPD) mode provides an ultra-low power state when data retention isn’t required.

Featuring a double data rate four-bit prefetch architecture, the LPDDR2 SDRAMs deliver high-speed operation with clock rates of 400MHz and 533MHz, and are available in commercial (-30℃ to +85℃) and industrial (-40℃ to +85℃) temperature ranges. The devices offer programmable read or write burst lengths of 4, 8, or 16; 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. The RoHS-compliant ICs are lead (Pb)- and halogen-free.

Device Specification Table

Alliance Memory offers an extensive line-up of mobile low-power SDRAMs to help designers meet the demand for reduced power consumption in portable electronics, including 64M, 128M, 256M, 512M, and 1GB LPDDR1 SDRAMs and 16GB LPDDR3 SDRAMs. 8GB 256M x 32 LPDDR2 SDRAMs in the 134-ball FBGA package will also be available soon.

Samples and production quantities of the LPDDR2 SDRAMs are available now.

NOR FLASH+PSRAM合成芯片 64Mb以上容量，数据及地址线并行，有没有两颗可以兼容的型号。

NOR FLASH主要用于存储程序，而PSRAM（或SDRAM）则是用于存储运行时的数据，单独的NOR FLASH 和PSRAM（或SDRAM）芯片，在引脚封装、接口定义、主频上是不兼容的，所以不能用一个元器件的封装来兼容两个不同类别的存储器。但针对手机应用，由于体积和重量限制，是有用将NOR FLASH 和PSRAM封装到一起的存储器芯片的。目前我们代理的存储器品牌ALLIANCE，有用于手机的存储器DDR1（256Mb,512Mb,1Gb和2Gb，宽度16位和32位，主频166MHZ和200MHZ）,DDR2（1Gb,2Gb,4Gb和8Gb，宽度16位和32位，主频400MHZ和533MHZ）如：4Gb的AS4C128M32MD2，8Gb的AS4C256M32MD2和DDR3（16Gb,宽度32位，主频667MHZ）：16Gb的AS4C512M32MD3-15BCN，没有这种将NOR FLASH 和PSRAM（SDRAM）封装到一起的存储器芯片。
