Embedded multimedia card (eMMC), host for controlling the eMMC, and methods of operating the eMMC and the host

摘要

A method of operating an eMMC system includes receiving a first command defining a first operation from the host, and storing the first command in a first command register among N command registers, and receiving a second command defining a second operation from the host, and storing the second command in a second command register among the N command registers, wherein the second command is received while the first operation is being performed.

主权项

1. An embedded multimedia card (eMMC) comprising:
a flash memory; and an eMMC controller configured to receive a first command from a host, send a first response for the first command to the host, and perform a first operation in response to the first command, wherein while performing the first operation, the eMMC receives a second command from the host, stores the second command, and sends a second response for the second command to the host, wherein the first operation comprises at least one among of:
the eMMC controller reading first read data from the flash memory in response to the first command;the eMMC controller storing the first read data in a first data buffer; andthe eMMC controller transferring the first read data stored in the first data buffer to the host.
