Abstract
A Solid State Drive (SSD) that includes a host connector receptacle for connecting to a host computer, a plurality of NAND devices and a nonvolatile memory controller. The nonvolatile memory controller is configured to perform program operations and read operations on memory cells of each of the NAND devices. The nonvolatile memory controller includes a program step circuit configured to initially program memory cells of each of the NAND devices using an initial program step voltage and is configured to change the program step voltage used to program the memory cells of each of the NAND devices during the lifetime of each of the NAND devices.
