Abstract

The present invention provides a memory controller and a memory system including the memory controller and an operating method for a memory device controlling a nonvolatile memory. The operation method includes: in response to an external write request, managing a program depth bitmap indicating an upper page programming state of each of a plurality of word lines of the nonvolatile memory; and in response to an external read request, based on the programming The information of the depth bitmap corresponding to the word line to be accessed is used to output one of a plurality of different read commands to the non-volatile memory.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2013-0024628 filed with the Korean Intellectual Property Office on Mar. 7, 2013, the entire contents of which are hereby incorporated by reference. technical field [0003] The inventive concepts described herein relate to memory controllers and memory systems that control and / or include non-volatile memory devices that store multi-bit data. Background technique [0004] Semiconductor memory is generally considered to be the most critical microelectronic component in the design of digital logic systems such as computer and microprocessor based applications ranging from satellites to consumer electronics. Thus, advances in the fabrication of semiconductor memories, including process enhancements and technology developments through scaling for higher densities and faster speeds, have helped other digital logic families set performance s...
