Witryna27 mar 2016 · Mar 27, 2016 at 8:14. 1. Yes, STM32 flash is a bit of a "gotcha" - that is not the only problem with it - normally you can read one page while writing/erasing another, but in STM32 the entire flash bus stalls, so no no code in flash runs - stalling execution for significant periods (tens of milliseconds). – Clifford. Witryna21 lut 2024 · 1. There's a third option: the CPU sends the data to the chip over a bus of whatever width. The chip collects the data in a small RAM buffer, and when it has all the data for a page, it overwrites the entire page with the data from the buffer. Even if the page has to be written all at once, that does not mean the CPU has to send the data …

Witryna"NAND Flash memory in embedded systems". "Program disturb occurs when a bit is unintentionally programmed from a “1” to a “0” during a page-programming event. … 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…
