Abstract:
The disclosed technology generally relates to apparatuses and methods of operating the same, and more particularly to cross point memory arrays and methods of accessing memory cells in a cross point memory array. In one aspect, an apparatus comprises a memory array. The apparatus further comprises a memory controller configured to cause an access operation, where the access operation includes application of a first bias across a memory cell of the memory array for a selection phase of the access operation and application of a second bias, lower in magnitude than the first bias, across the memory cell for an access phase of the access operation. The memory controller is further configured to cause a direction of current flowing through the memory cell to be reversed between the selection phase and the access phase.
