Abstract: An eMMC includes flash memory including an extended card specific data (CSD) register (“EXT_CSD register”), and an eMMC controller that controls operation of the flash memory. The eMMC controller is receives a clock from a host via a clock line, receives a SEND_EXT_CSD command from the host via a command line, and provides the host with eMMC information stored in the EXT_CSD register via a data bus in response to the SEND_EXT_CSD command, the eMMC information including maximum operating frequency information for the eMMC.

Abstract translation: eMMC包括闪存，包括扩展卡特定数据（CSD）寄存器（“EXT_CSD寄存器”）和控制闪存的操作的eMMC控制器。 eMMC控制器通过时钟线从主机接收时钟，通过命令行从主机接收SEND_EXT_CSD命令，并通过SEND_EXT_CSD命令经由数据总线向主机提供存储在EXT_CSD寄存器中的eMMC信息， eMMC信息包括eMMC的最大工作频率信息。

Abstract: An embedded multimedia card (eMMC) includes a flash memory and an eMMC controller that controls operation of the flash memory. The eMMC controller includes a command register that receives from a host a command set defining a next operation specifying second data simultaneously with a transfer of first data specified by a current operation, a first memory that stores the first data, and a second memory that stores the second data.
