STORAGE DEVICE INCLUDING RANDOM ACCESS MEMORY DEVICES AND NONVOLATILE MEMORY DEVICES

摘要

A storage device includes random access memories, nonvolatile memory devices, a controller configured to control the nonvolatile memory devices, and a driver circuit configured to receive a command and an address from an external device, output a buffer command according to the command and the address, and transmit the command and the address to one of a first channel connected to the random access devices and a second channel connected to the controller according to the command and the address. The storage device further includes a plurality of data buffers configured to communicate with the external device and electrically connect the external device to one of a third channel connected to the random access memory devices and a fourth channel connected to the controller in response to the buffer command. Each of the data buffers includes a FIFO (first-in first-out) circuit.
