发明名称 Method of rewriting program in a flash microcomputer
摘要 A method of rewriting a boot program into a memory device including at least first and second memory blocks to which a boot program can be electrically written and from which a boot program can be electrically erased, includes the steps of (a) erasing data stored in the second memory block to which a new boot program is to be written, (b) writing a new boot program into the second memory block, (c) changing an address of the second memory block such that the second memory block can be recognized as the new primary boot block, (d) erasing an existing boot program from the first memory block, and leaving the second memory block as the primary boot block until a further new boot program is written into the memory device.
