How is memory erased in flash
Web25 apr. 2024 · The Erasable Programmable Read Only Memory is a memory chip that does not lose data even when the power is switched off. This is a non-volatile memory type i.e. it retains data even when the power is switched off. Each EPROM is individually programmed by an electronic device. After that, the data can be erased by exposing the … Web3 aug. 2024 · from some posts I get that the default state of Flash Memory (after erase) is "0", instead of "1", which is normal for Flash memory: Flash programming granularity LPC55 .
