Abstract
A memory system includes a memory and a controller. The memory includes: first memory cells; a first word line connected to these; second memory cells; and a second word line connected to these. The controller is configured to store first write data used for a write to first memory cells and second write data used for a write to second memory cells. The controller is configured to calculate rewrite data based on the first write data and the second write data. The memory is configured to perform: a first write operation of performing a write on first memory cells based on the first write data input from the controller; and a rewrite operation of performing a write on a part of first memory cells based on the rewrite data input from the controller.
Claims20
A memory system comprising:
- a memory that includes:
- a plurality of first memory cells;
- a first word line connected to the plurality of first memory cells;
- a plurality of second memory cells;
- and
- a second word line connected to the plurality of second memory cells;
- and
- a controller connected to the memory, wherein
- the controller is configured to be able to store:
- first write data used for a write to the plurality of first memory cells;
- and
- second write data used for a write to the plurality of second memory cells, the write being performed after the write to the plurality of first memory cells,
- the controller is configured to be able to calculate rewrite data based on the first write data and the second write data, and
- the memory is configured to be able to perform:
- a first write operation of performing a write on the plurality of first memory cells based on the first write data input from the controller;
- and
- a rewrite operation of performing a write on a part of the plurality of first memory cells based on the rewrite data input from the controller.
A control method of a memory system, wherein
- the memory system comprises:
- a memory that includes:
- a plurality of first memory cells;
- a first word line connected to the plurality of first memory cells;
- a plurality of second memory cells;
- and
- a second word line connected to the plurality of second memory cells;
- and
- a controller connected to the memory, wherein
- the controller stores:
- first write data used for a write to the plurality of first memory cells;
- and
- second write data used for a write to the plurality of second memory cells, the write being performed after the write to the plurality of first memory cells,
- the controller calculates rewrite data based on the first write data and the second write data, and
- the memory performs:
- a first write operation of performing a write on the plurality of first memory cells based on the first write data input from the controller;
- and
- a rewrite operation of performing a write on a part of the plurality of first memory cells based on the rewrite data input from the controller.
