Abstract
A memory device including a page buffer is part of a memory system. The memory device includes first memory cells, each configured to be programmed to have a threshold voltage corresponding to any one of a plurality of program states. The memory device also includes data latches configured to respectively store a plurality of pieces of first logical page data to be stored in the first memory cells. The memory device further includes a pre-sensing latch configured to store data sensed through a pre-verify operation. The pre-sensing latch stores second logical page data to be stored in second memory cells when a main verify operation for a threshold program state, among the plurality of program states, has passed.
Claims30
A memory device, comprising:
- first memory cells, each configured to be programmed to have a threshold voltage corresponding to any one of a plurality of program states;
- data latches configured to respectively store a plurality of pieces of first logical page data to be stored in the first memory cells;
- and
- a pre-sensing latch configured to store data sensed through a pre-verify operation,
- wherein the pre-sensing latch stores second logical page data to be stored in second memory cells when a main verify operation for a threshold program state, among the plurality of program states, has passed.
A memory device, comprising:
- a memory block including a first physical page and a second physical page;
- data latches configured to respectively store a plurality of pieces of first logical page data to be stored in the first physical page;
- and
- a cache latch configured to store second logical page data to be stored in the second physical page,
- wherein any one of the data latches is configured to, when a program operation of storing the plurality of pieces of first logical page data in the first physical page has failed, provide any one of the plurality of pieces of first logical page data to an external memory controller.
A memory system, comprising:
- a memory device including a first physical page and a second physical page;
- and
- a memory controller configured to provide a plurality of pieces of first logical page data to be stored in the first physical page and second logical page data to be stored in the second physical page, and thereafter obtain any one of the plurality of pieces of first logical page data from the memory device in response to a failure of a program operation.
A page buffer, comprising:
- data latches configured to respectively store a plurality of pieces of first logical page data to be stored in a first physical page;
- a main sensing latch configured to store result information of a main verify operation;
- and
- a pre-sensing latch configured to store result information of a pre-verify operation,
- wherein, in response to a program suspend command,
- any one of the data latches transfers any one of the plurality of pieces of first logical page data to the pre-sensing latch, and
- the main sensing latch reflects the result information of the main verify operation in the plurality of pieces of first logical page data and stores data sensed through a read operation.
