Abstract
An apparatus has a controller and an array of memory cells, including a first section comprising a plurality of rows and a second section comprising a plurality of rows. The controller configured to, in association with wear leveling, transfer data stored in a first row of the first section from the first row to a register, transfer the data from the register to a destination row of the second section while data in a second row of the first section is being sensed.
Claims20
An apparatus, comprising:
- a controller configured to:
- in response to a wear leveling command associated with a wear leveling operation, cause first data stored in a first row of a first array of memory cells of a memory device to be transferred to a register of the memory device without communicating the first data off the memory device;
- and
- in response to a subsequent wear leveling command associated with the wear leveling operation, cause the first data to be transferred from the register to a row of a second array of memory cells of the memory device while second data stored in a second row of the first array of memory cells is being sensed and without communicating the first data and the second data off the memory device.

A system, comprising:
- a memory device, comprising:
- a first array of memory cells;
- a second array of memory cells;
- and
- a register coupled to the first and second arrays of memory cells;
- and
- a controller coupled to the memory device and configured to:
- in response to a wear leveling command, transfer first data stored in a first row of the first array of memory cells to the register without transferring the first data off the memory device;
- in response to a subsequent wear leveling command, transfer, in parallel:
- second data stored in a second row of the first array of memory cells to the register without transferring the second data off the memory device;
- and
- the first data from the register to a row of the second array of memory cells without transferring the first data off the memory device.

A method, comprising:
- in response to a wear leveling command:
- transferring data stored in a first row of a first array of memory cells of a memory device to a first register without transferring the data off the memory device;
- and
- transferring the data from the first register to a second register without transferring the data off the memory device;
- and
- in response to a subsequent wear leveling command, transferring, in parallel:
- the data from the second register to a row of a second array of memory cells of the memory device without transferring the data off the memory device;
- and
- data stored in a second row of the first array of memory cells to the first register without transferring the data off the memory device.
