Abstract

An apparatus is described. An apparatus includes controller logic circuitry to perform a program-verify programming process to a flash memory chip. The program-verify programming process is to reduce a size of a pre-program verify (PPV) bucket in response to a number of cells being fully programmed to a same digital state. The number of cells are less than a total number of cells to be programmed to the same digital state.
