Abstract
A memory system having a memory controller and a memory device coupled to the memory controller. The memory controller outputs a write data value to the memory device. The memory device receives the write data value from the memory controller, and compares the write data value with a mask key value. If the write data value matches the mask key value, the memory device does not store the write data value. If the write data value does not match the mask key value, the memory device stores the write data value.
