Flash memory device e.g. flash memory card, for use in computer system e.g. personal computer, has floating gate type memory transistor as selection transistor of memory block's NAND cell unit for storing random data in memory blocks
The flash memory device has a set of memory blocks, where each memory block includes a NAND cell unit having a selection transistor e.g. string selection transistor (SST) or a ground selection transistor (GST), connected in series to a set of memory cells (MC) controlled by respective word lines. The selection transistor is a floating gate type memory transistor for storing random data in the memory blocks. The selection transistor is configured to have a variably programmable threshold voltage. Independent claims are also included for the following: (1) a method for programming a flash memory device (2) a solid state memory module for a computer system.
