I/O partitioning system and methodology to reduce band-to-band tunneling current during erase

A system is provided for reducing band-to-band tunneling current during Flash memory erase operations. The system includes a memory sector divided into (N) I/O subsectors, N being an integer, and a drain pump to generate power for associated erase operations within the N I/O subsectors. An erase seq...

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