AN99111 - Parallel NOR Flash Memory: An Overview

WebFlash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the … One limitation of flash memory is that it can be erased only a block at a time. This generally sets all bits in the block to 1. Starting with a freshly erased block, any location within that block can be programmed. However, once a bit has been set to 0, only by erasing the entire block can it be changed back to 1. In other words, flash memory (specifically NOR flash) offers random-access rea… enderal phasmalist https://amgsgz.com

WebThe fact that the STM32 allows to write a arbitrary value to an erased address and later reset that to zero makes this possible. In many flash devices, erasing a page/block/sector/whatever will require internally programming all bits to zero () and then performing an erase cycle on all bits simultaneously. WebPage is the smallest data unit that the VM manages. Block is a sequence of bits and bytes. Block is made up of sectors. A page is made up of unit blocks or groups of blocks. A block is made up of either one sector or many sectors (2, 4, 6...), which means blocks have varied in sizes. Pages have a fixed size.
