Nor flash bad
WebI thought for both NAND and NOR, a high positive voltage was used across gate/source to quantum-tunnel out the stored charge (thus setting it to a 1). Looks like I'm missing something. Also any good reference to literature for NAND/NOR circuitry organization would be appreciated. \$\endgroup\$ – Web6 de jan. de 2024 · I have a PS3 Slim 2001A, and was attempting to install CFW to my system with Psxploit. I went through Nor Flash Memory Dumper and backed up the dump.hex into a safe spot. I then went through the necessary steps and ran Nor Flasher. I got the Nor Flasher Operation Completed Message and then preceded to to put the cfw …

Web2 de ago. de 2024 · However, NAND flash memory density is much, much higher than NOR flash. So it stands to reason that it would be more fragile. The document you linked to is 15 years old, and not relevant anymore. Note that the listed maximum density for NAND flash is 128 Megabyte. NAND flash development has been extremely active for the last 15 years. WebFigure 2 shows a comparison of NAND Flash an d NOR Flash cells. NAND efficiencies are due in part to the small number of metal co ntacts in the NAND Flash string. NAND …
