Memory system, computing system including the same and method of operating memory system
First Claim
1. A memory system comprising:
- a semiconductor memory device; and
a memory controller configured to control the semiconductor memory device, and receive a first command to acquire data stored in the semiconductor memory device, and a second command to write data in the semiconductor memory device from a host,wherein the memory controller completes preparation to perform a first operation corresponding to the first command by performing a first booting operation when power is up, and outputs a first command ready signal to the host regardless of a request of the host, and then completes preparation to perform a second operation corresponding to the second command by performing a second booting operation after the first booting operation, and outputs a second command ready signal to the host regardless of a request of the host, andwherein the first command ready signal and the second command ready signal comprise command type information and state information, respectively, the command type information specifying the first command or the second command, and the state information containing information on whether the preparation to perform the operation corresponding to a command type is completed.

Abstract
Disclosed is a memory system including: a semiconductor memory device; and a memory controller suitable for controlling the semiconductor memory device, and receiving a first command for accessing the semiconductor memory device, and a second command of a different type from that of the first command from a host. The memory controller completes preparation to perform an operation corresponding to the first command by performing a first booting operation when power is up, and outputs a first command ready signal to the host. The memory controller completes preparation to perform an operation corresponding to the second command by performing a second booting operation after the first booting operation, and outputs a second command ready signal to the host.

15. A method of operating a memory system in which a memory controller controls a semiconductor memory device and receives a first command to acquire data stored in the semiconductor memory device and a second command to write data in the semiconductor memory device from a host, the method comprising:
-
completing preparation to perform a first operation corresponding to the first command by performing a first booting operation when power is up; outputting a first command ready signal to the host regardless of a request of the host when the preparation to perform the first operation corresponding to the first command is completed; completing preparation to perform a second operation corresponding to the second command by performing a second booting operation after the first booting operation; and outputting a second command ready signal to the host regardless of a request of the host when the preparation to perform the second operation corresponding to the second command is completed, wherein the first command ready signal and the second command ready signal comprise command type information and state information, respectively, the command type information specifying the first command or the second command, and the state information containing information on whether the preparation to perform the operation corresponding to a command type is completed. - View Dependent Claims (16, 17, 18, 19, 20)
