emmc5.1 协议 英文原档。 The e•MMC is a managed memory capable of storing code and data. It is specifically designed for mobile devices. The e•MMC is intended to offer the performance and features required by mobile devices while maintaining low power consumption. The e•MMC device contains features that support high throughput for large data transfers and performance for small random data more commonly found in code usage. It also contains many security features.

EMMC5.1协议标准 This document provides a comprehensive definition of the e•MMC Electrical Interface, its environment, and handling. It also provides design guidelines and defines a tool box of macro functions and algorithms intended to reduce design-in overhead.
