Abstract:
Methods and apparatus to provide dynamic window to improve NAND (Not And) memory endurance are described. In one embodiment, a program-erase window associated with a NAND memory device is dynamically varied by starting with a higher erase verify (TEV) voltage and lowering the TEV voltage with subsequent cycles over a life of the NAND memory device based on a current cycle count value. Alternatively, the program-erase window is dynamically varied by starting with a higher erase verify (PV) voltage and erase verify (TEV) voltage and lowering the PV and TEV voltages with subsequent cycles over a life of the NAND memory device based on the current cycle count value. Other embodiments are also disclosed and claimed.

Claim (Index 1):
An apparatus comprising:\n a memory controller logic to apply a first trim profile to a flash memory storage device; and the first trim profile to dynamically cause a program-erase window to vary by starting with a higher erase verify (TEV) voltage and lowering the TEV voltage with subsequent cycles over a life of the flash memory storage device based on a current cycle count value, wherein the memory controller logic is to apply a second trim profile to the flash memory storage device in response to a determination that the current cycle count value has exceeded a threshold value or in response to occurrence of a failure condition.
