根据不同的生产厂商和不同的应用,闪存卡大概有SmartMedia(SM卡)、CompactFlash(CF卡)、MultiMediaCard(MMC卡)、SecureDigital(SD卡)、MemoryStick(记忆棒)、XD-PictureCard(XD卡)和微硬盘(MICRODRIVE)这些闪存卡虽然外观、规格不同,但是技术原理都是相同的。NOR型与NAND型闪存的区别很大,打个比方说,NOR...
尺寸:24mm*32mm*14mm MMC卡时钟频率是20MHz,比SD卡少两个PIN,只有一位数据带宽,所以最大传输速率为2.5MHz。 eMMC 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内存,使得是手机...
SD卡是(secure digital memory card)安全数码卡,是一种基于半导体快闪记忆器的新一代记忆设备,是在MMC基础上发展起来的,增加了两个主要特色: 可以设置所存储的使用权限,防止数据被他人复制;第二是传输速度比2.11版mmc卡快。 特性: 1)可选通信协议:SD模式和SPI模式 2)可变时钟频率:0~25MHz 3)通信电压范围:2.0...
