                              eMMC技术详解

                              2015-03-31 13:53来源:中国存储网
                              导读:eMMC 是针对手机或平板电脑等产品的内嵌式存储器标准规格。现在主流旗舰手机都采用eMMC 5.0规格的闪存或者更新的UFS 2.0闪传标准,有着比eMMC 5.0更快的读取性能。

                              eMMC=NAND Flash+闪存控制芯片+标准接口封装

                              eMMC (Embedded Multi Media Card) 为MMC协会所订立的、主要是针对手机或平板电脑等产品的内嵌式存储器标准规格。eMMC的一个明显优势是在封装中集成了一个控制器,它提供标准接口并管理闪存,使得手机厂商就能专注于产品开发的其它部分,并缩短向市场推出产品的时间。这些特点对于希望通过缩小光刻尺寸和降低成本的NAND供应商来说,同样的重要。

                              现在主流旗舰手机都采用eMMC 5.0规格的闪存的潮流中,一种新的闪传规格悄然出现,它就是UFS 2.0闪传标准,有着比eMMC 5.0更快的读取性能。(参见从eMMC到ufs 看手机闪存变化了什么并非eMMC/ufs,苹果iPhone6s内部闪存是NVMe
