There are many examples but most of them use the SPL API or low-level register operations. I am using the HAL libraries. And I cannot find a function to erase just one page (in stm32f4xx_hal_flash.c and stm32f4xx_hal_flash_ex.c).

WebQuoting from expert. " NOR flash must be erased and written in blocks, but for read access it can be treated just like an async memory attached to the memory interface. So it needs address lines equivalent to its memory size. For NAND flash, everything must be done in terms of pages/blocks (reads/writes can happen on smaller pages, erases still ... The pages are typically 512, [98] 2,048 or 4,096 bytes in size. Associated with each page are a few bytes (typically 1/32 of the data size) that can be used for storage of an error correcting code (ECC) checksum . Typical block sizes include: 32 pages of 512+16 bytes each for a block size (effective) of 16 KiB. Ver mais Flash 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 NOR Ver mais Block erasure 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. … Ver mais NOR and NAND flash differ in two important ways: • The connections of the individual memory cells are different. • The interface provided for reading and writing the memory is different; NOR allows random access, while NAND allows … Ver mais Background The origins of flash memory can be traced back to the development of the floating-gate MOSFET (FGMOS) Ver mais Flash memory stores information in an array of memory cells made from floating-gate transistors. In single-level cell (SLC) devices, each cell stores only one bit of information. Ver mais The low-level interface to flash memory chips differs from those of other memory types such as DRAM, ROM, and EEPROM, which support bit … Ver mais Because of the particular characteristics of flash memory, it is best used with either a controller to perform wear leveling and error correction or … Ver mais
