The reason a flash memory stick or solid state disk has no bad blocks is that your computer doesn't get to see them. A device can be manufactured with a number of spare blocks, and a controller chip that provides the USB or SATA interface.

WebI had to remove the const from the declaration to make it work. My complete solution consists of two parts (as already said above but with some further modifications): FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 896K /* origin size was 1024k, subtracted size of DATA */ DATA (rx) : ORIGIN = 0x080E0000, LENGTH = 128K.
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.

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.
