Introduction

This document provides information about the 1.8 Volt Intel StrataFlash

®

Wireless memory device

(L18). This document describes the device features, operation, and specifications.

1.1

Nomenclature

1.8 V:

V

CC

voltage range of 1.7 V – 2.0 V (except where noted)

1.8 V Extended Range:

V

CCQ

voltage 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 L18 flash memory device has two block

sizes: 16K-Word, and 64K-Word.

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.
