技术问答

ALLIANCE Memory公司，总部位于美国，是全球领先的高性能存储器及存储扩展逻辑产品厂家，Alliance Memory的wafer及封测厂家均由全球知名厂家提供，保证一流的品质。Alliance Memory以其供货稳定、产品生命周期长、价格基本不浮动的特点广受客户好评。

2018年10月24日，美国Alliance Memory公司推出了一个全新的高速CMOS伪SRAM（PSRAM）系列。其产品密度从8Mb到128Mb，封装结构为6.0 mm x 7.0 mm x 1.0 mm 的48-ball FPBGA和4.0 mm by 4.0 mm by 1.0 mm 的49-ball FPBGA。该系列产品结合了SRAM和DRAM的最优特性，为产品研发工程师提供了易于使用、低功耗和低成本的内存解决方案，可应用在无线产品、汽车、网络和工业应用方面。

图1 新型PSRAM系列芯片的功能模块图

此次发布的新系列产品将SRAM接口集成在了高密度的DRAM内核上，并且搭载了片上刷新电路，可做到免刷新模式。该系列产品具有高带宽和低功耗的特点，可用来取代移动电话和PDA等便携式电子设备中的SRAM，也可用作突发NOR Flash（或非型闪存）应用的配套芯片。

该系列中AS1C1M16PL-70BIN、AS1C1M16P-70BIN、AS1C2M16P-70BIN、AS1C512K16PL-70BIN、AS1C512K16P-70BIN的接口与异步型SRAM兼容。AS1C4M16PL-70BIN和AS1C8M16PL-70BIN可用作CellularRAM（蜂窝型RAM，主要用于新型G网手机等）的PSRAM，其采用多路复用地址和数据总线技术，可获得更高的带宽。该系列产品支持异步和突发操作功能，采用4、8、16或32字节的可读写突发数据输入长度，或者选用连续的突发数据输入方式。

图2 新型PSRAM系列芯片的主要参数表

在工业温度范围内，该系列PSRAM可提供的快速接入速度为70纳秒，并且能在1.75V至1.95V，或2.6V至3.3V的单一电源下工作。另外，其自带有多种节能功能，包括自动温度补偿自刷新（ATCSR），部分阵列自刷新（PaSR）和深功率下降（PDP）模式。

该系列芯片的产品密度有8M、16M、32M、64M和128M，其中8M与18M芯片又分为适用1.7~1.95V电源电压和2.6~3.3V电源电压两种型号，所以该系列芯片总共有7种不同型号组成（详细参数请参见图表2）。该系列芯片的可适应工作温度范围为-30°C（或-40°C）~+85°C，有一定的耐低温、高温工作能力。

新型PSRAM系列芯片的主要特点：

• 产品密度从8M~128M，多型号可供选择

• 结合SRAM和DRAM的优点，易于使用、低功耗和低成本

• 免刷新模式

• 高带宽，低功耗

• 与异步型SRAM兼容

• 支持异步和突发操作功能

• 快速接入70ns

• 低电压单电源工作（1.7~1.95V或2.6~3.3V）

• 工作温度范围：-30°C（或-40°C）~+85°C

新型PSRAM系列芯片的典型应用：

• 移动电话

• PDA

• 笔记本电脑

• 突发或非型闪存（Burst NOR Flash）的配套芯片

• 汽车电子配件

• 网络配件

• 工业应用

产品变更通知及停产信息 - ALLIANCE - April 26th 2024 PDF 英文下载

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。
