Abstract
A device, method, machine-readable medium, and system are disclosed. In one embodiment the device is a memory controller capable of modifying a reference voltage to a persistent moving read reference (MRR) voltage level for use during one or more subsequent reads to a non-volatile memory array. This modification is in response to a change in a reference voltage supplying the non-volatile memory array from a previous reference voltage level to a temporary MRR voltage level.
