Abstract
Memory devices are shown that include a body region and a connecting region that is formed from a semiconductor with a lower band gap than the body region. Connecting region configurations can provide increased gate induced drain leakage during an erase operation. Configurations shown can provide a reliable bias to a body region for memory operations such as erasing, and containment of charge in the body region during a boost operation.
