Abstract
A low-current FN channel for Erase, Program, Program-Inhibit and Read operations is disclosed for any non-volatile memory using FN-tunneling scheme for program and erase operation, regardless NAND, NOR, and EEPROM and regardless PMOS or NMOS non-volatile cell type. As a result, all above NMV memories can use the disclosed LV, compact PGM buffer to replace the traditional HV PGM buffer for saving in the silicon area and power consumption. The page buffer is used to store new loaded data for new writing and to convert the stored data into the required BL HV voltage for either Erase or Program operations according to the stored data. In addition, the simpler on-chip State-machine design can be achieved with the superior quality of NVMs of this disclosure.
