摘要
PURPOSE: An operation method of a nonvolatile memory device is provided to secure a stable read margin by performing a reading operation of a compensated voltage.;CONSTITUTION: Data to be stored is inputted through an IO buffer unit(S601). A temperature data measured at a temperature information generator is stored(S603). A program operation is performed so that the data is stored in a memory cell(S605). A verification operation of a programmed cell is performed(S607). If the verification fails, a program voltage is increased according to ISPP(Increasing Step Pulse Program) mode(S609).;COPYRIGHT KIPO 2011
