Norflash chip erase
WebThis reference design describes the use of Lattice programmable devices to implement a NOR Flash memory controller through a WISHBONE bus. It supports several common operational modes of a NOR Flash, including reset operation, autoselect manufacturer ID operation, read operation, program operation, chip erase operation and sector erase … WebTo erase a NOR flash cell (resetting it to the "1" state), a large voltage of the opposite polarity is applied between the CG and source terminal, pulling the electrons off the FG through quantum tunneling. Modern NOR flash …
