Abstract
An apparatus can have a memory comprising an array of resistance variable memory cells and a controller. The controller can be configured to receive to a dedicated command to write all cells in a number of groups of the resistance variable memory cells to a first state without transferring any host data corresponding to the first state to the number of groups. The controller can be configured to, in response to the dedicated command, perform a read operation on each respective group to determine states of the cells in each respective group, determine from the read operation any cells in each respective group programmed to a second state, and write only the cells determined to be in the second state to the first state.
