Abstract: A memory device comprises a memory array having corresponding first access control bits to control access thereto. A second set of access control bits is provided to control write access to the first access control bits. The memory array is divided into memory blocks, each block having a corresponding access control bit. At least one such block is further subdivided into pages, each page having a corresponding control bit.

System for updating program stored in eeprom by storing new version into new location and updating second transfer vector to contain starting address of new version
Arthur J. Beaverton,Thomas A. Hunt +1 more
- 14 Jun 1989
TL;DR: In this paper, transfer vectors are used to provide indirect accessing of subroutines resident in the firmware and the window of vulnerability to errors during the updating process is minimized by only updating a page of memory containing the transfer vector that points to the old version of the subroutine after the new version has been stored.
