Abstract
A program method of a memory device include determining whether valid data is stored in memory cells of a word line adjacent to a selection word line upon which a program operation is to be performed; when the valid data is not stored in the memory cells of the word line adjacent to the selection word line, performing, based on data to be written to the selection word line, a pre-program operation on the word line adjacent to the selection word line; and after the performing of the pre-program operation, performing, based on a program command, the program operation on the selection word line.
Claims20
A program method of a memory device, the method comprising:
- determining whether valid data is stored in memory cells of a word line adjacent to a selection word line upon which a program operation is to be performed;
- when the valid data is not stored in the memory cells of the word line adjacent to the selection word line, performing, based on data to be written to the selection word line, a pre-program operation on the word line adjacent to the selection word line;
- and
- after the performing of the pre-program operation, performing, based on a program command, the program operation on the selection word line.
A memory system comprising:
- a non-volatile memory device comprising a memory cell array which is connected to a plurality of word lines and a plurality of bit lines;
- and
- a memory controller configured to control, based on a program command which is received from a host, an operation of the non-volatile memory device,
- the non-volatile device and the memory controller being configured such that, when valid data is not stored in memory cells of a word line which is adjacent to a selection word line of the non-volatile memory device upon which a program operation is to be performed, at least one of the non-volatile device and the memory controller,
- performs a pre-program operation, based on data to be written to the selection word line, on the word line adjacent to the selection word line, and then,
- performs the program operation according to the program command.
A method comprising:
- performing a programming operation including programming write data into memory cells of a first word line from among a plurality of word lines included in a memory cell array of a memory device;
- and
- preforming a preliminary operation before performing the programming operation, the preliminary operation including,
- determining preliminary data based on the write data, and
- programming the preliminary data into memory cells of an adjacent word line, the adjacent word line being a word line, from among the plurality of word lines, that is adjacent to the first word line.
