      PRODUCT DESCRIPTION
      2.1
      Memory Blocking Organization
      This product family features an asymmetrically-
      blocked architecture providing system memory
      integration. Each erase block can be erased
      independently of the others up to 100,000 times for
      commercial temperature or up to 10,000 times for
      extended temperature. The block sizes have been
      chosen to optimize their functionality for common
      applications of nonvolatile storage. The combination
      of block sizes in the boot block architecture allow
      the integration of several memories into a single
      chip. For the address locations of the blocks, see
      the memory maps in Figures
      4 and 5.
      2.1.1
      ONE 16-KB BOOT BLOCK
      The boot block is intended to replace a dedicated
      boot PROM in a microprocessor or microcontroller-
      based system.
      The 16-Kbyte (16,384 bytes) boot
      block is located at either the top (denoted by -T
      suffix) or the bottom (-B suffix) of the address map
      to accommodate different microprocessor protocols
      for boot code location. This boot block features
      hardware controllable write-protection to protect the
      crucial microprocessor boot code from accidental
      modification. The protection of the boot block is
      controlled using a combination of the V
      PP
      , RP#, and
      WP# pins, as is detailed in Section
      3.4.
      2.1.2
      TWO 8-KB PARAMETER BLOCKS
      The boot block architecture includes parameter
      blocks to facilitate storage of frequently updated
      small parameters that would normally require an
      EEPROM. By using software techniques, the byte-
      rewrite functionality of EEPROMs can be emulated.
      These techniques are detailed in Intel’s application
      note AP-604, Using Intel’s Boot Block Flash
      Memory Parameter Blocks to Replace EEPROM
      .
      Each boot block component contains two parameter
      blocks of 8 Kbytes (8,192 bytes) each. The
      parameter blocks are not write-protectable.
      2.1.3
      ONE 96-KB + ONE 128-KB MAIN
      BLOCK
      After the allocation of address space to the boot
      and parameter blocks, the remainder is divided into
      main blocks for data or code storage. Each 2-Mbit
      device contains one 96-Kbyte (98,304 byte) block
      and one 128-Kbyte (131,072 byte) block. See the
      memory maps for each device for more information.
