Memory system and operating method thereof

Abstract

There are provided a memory system and an operating method thereof. The memory system includes a semiconductor memory configured to perform a memory operation and perform a suspend operation of suspending a currently performed memory operation and a controller configured to control the memory operation. The controller controls the semiconductor memory to perform the suspend operation in a suspension-allowed period by determining a detailed operation period of the currently performed memory operation.

What is claimed is: 
     
         1 . An operating method for a controller for controlling a memory device, the operating method comprising controlling the memory device to:
 perform a second memory operation while suspending a first memory operation which is currently being performed, during a suspension-allowed period of the first memory operation; and   resume the suspended first memory operation upon completion of the second memory operation.   
     
     
         2 . An operating method of a memory device, the operating method comprising:
 performing a second memory operation while suspending a first memory operation, which is currently being performed, during a suspension-allowed period of the first memory operation; and   resuming the suspended first memory operation upon completion of the second memory operation.
