1.0
Introduction
This document provides information about the Intel StrataFlash
®
wireless memory device (L18).
This document describes the device features, operation, and specifications.
1.1
Nomenclature
1.8 V:
range of 1.7 V – 2.0 V (except where noted)
1.8 V Extended Range:
range of 1.35 V – 2.0 V
VPP = 9.0 V:
V
PP
voltage range of 8.5 V – 9.5 V
Block:
A group of bits, bytes or words within the flash memory array that erase simultaneously
when the Erase command is issued to the device. The Intel StrataFlash® Wireless Memory (L18)
has two block sizes: 16-Kword, and 64-Kword.
Main block:
An array block that is usually used to store code and/or data. Main blocks are larger
than parameter blocks.
Parameter block:
An array block that is usually used to store frequently changing data or small
system parameters that traditionally would be stored in EEPROM.
Top parameter device:
Previously referred to as a top-boot device, a device with its parameter
partition located at the highest physical address of its memory map. Parameter blocks within a
parameter partition are located at the highest physical address of the parameter partition.
Bottom parameter device:
Previously referred to as a bottom-boot device, a device with its
parameter partition located at the lowest physical address of its memory map. Parameter blocks
within a parameter partition are located at the lowest physical address of the parameter partition.
Partition:
A group of blocks that share common program/erase circuitry. Blocks within a partition
also share a common status register. If any block within a partition is being programmed or erased,
only status register data (rather than array data) is available when any address within that partition
is read.
Main partition:
A partition containing only main blocks.
Parameter partition:
A partition containing parameter blocks and main blocks.
