Memory device, memory system, and method of operating the memory system

Abstract

A method of operating a memory system includes programming, in a memory device, K logical pages stored in a page buffer circuit into a memory cell array, reading, from the memory device, the K logical pages programmed into the memory cell array into the page buffer circuit after a first delay time elapses, transmitting, in a memory controller, N−K logical pages to the memory device, and programming, in the memory device, N logical pages into the memory cell array based on the read K logical pages and the N−K logical pages, wherein K is a positive integer and N is a positive integer greater than K.
