I/O PARTITIONING SYSTEM AND METHODOLOGY TO REDUCE BAND-TO-BAND TUNNELING CURRENT DURING ERASE

摘要

A system (10a) is provided for reducing band-to-band tunneling current during flash memory erase operations. The system (10a) includes an I/O memory sector (20) divided into (N) subsectors, N being an integer, and a drain pump (40) to generate power for associated erase operations within the N subsectors. An erase sequencing subsystem (60) generates N pulses to enable the erase operations within each of the N subsectors in order to reduce band-to-band tunneling current provided by the drain pump (40).
