Abstract
A method of controlling a memory device includes receiving a write instruction; starting a write operation to a first address in response to the write instruction; receiving a first read instruction of the first address; suspending the write operation; and applying a read voltage to a word line corresponding to the first address in a first read operation in response to the first read instruction.
Claims18
A method of controlling a memory device, the method comprising:
- receiving a write instruction;
- starting a write operation to a first address in response to the write instruction;
- receiving a first read instruction of the first address;
- suspending the write operation;
- applying a read voltage to a word line corresponding to the first address in a first read operation in response to the first read instruction;
- and
- transmitting write data of a first memory cell held by a latch circuit to a data register as read data,
- wherein the first memory cell is connected to the word line and the writing of the write data to the first memory cell is not completed.
