Intel® Wireless Flash Memory (W18)
1.0 Introduction
Word
2 bytes or 16 bits.
Signal
Voltage
Names are in all CAPS (see Section 4.2, “Signal Descriptions” on page 23.)
Applied to the signal is subscripted for example V

Throughout this document, references are made to top, bottom, parameter, and partition. To clarify
these references, the following conventions have been adopted:
Block
A group of bits (or words) that erase simultaneously with one block erase instruction.
Main block
Parameter block
Contains 32 Kwords.
Contains 4 Kwords.
Block Base
Address (BBA)
The first address of a block.
Partition
A group of blocks that share erase and program circuitry and a common Status Register.
Partition Base
Address (PBA)
The first address of a partition. For example, on a 32-Mbit top-parameter device partition number 5 has a
PBA of 0x140000.
Located at the highest physical device address. This partition may be a main partition or a parameter
partition.
Top partition
Located at the lowest physical device address. This partition may be a main partition or a parameter
partition.
Bottom partition
Main partition
Contains only main blocks.
Parameter
partition
Contains a mixture of main blocks and parameter blocks.
Top parameter
device (TPD)
Has the parameter partition at the top of the memory map with the parameter blocks at the top of that
partition. This was formerly referred to as a Top-Boot device.
Bottom parameter Has the parameter partition at the bottom of the memory map with the parameter blocks at the bottom of
device (BPD) that partition. This was formerly referred to as a Bottom-Boot Block flash device.
