operation in another sector within the same
device
GENERAL DESCRIPTION
AMD’s 5.0 V-only Flash Memory PC Card provides the
highest system level performance for data and file stor-
age solutions to the portable PC market segment. Man-
ufactured with AMD’s Negative Gate Erase, 5.0 V-only
technology, the AMD 5.0 V-only Flash Memory Cards
are the most cost-effective and reliable approach to
single-supply Flash memory cards. Data files and ap-
plication programs can be stored on the “C” series
cards. This allows OEM manufacturers of portable sys-
tems to eliminate the weight, high power consumption
and reliability issues associated with electromechanical
disk-based systems. The “C” series cards also allow to-
day’s bulky and heavy battery packs to be reduced in
weight and size. Typically only two “AA” alkaline batter-
ies are required for total system operation. AMD’s
Flash Memory PC Cards provide the most efficient
method to transfer useful work between different hard-
ware platforms. The enabling technology of the “C” se-
ries cards enhances the productivity of mobile workers.
CIA/JEIDA international standard. AMD’s Flash
Memory Cards can be read in either a byte-wide or
word-wide mode which allows for flexible integration
into various system platforms. Compatibility is assured
at the hardware interface and software interchange
specification. The Card Information Structure (CIS) or
Metaformat, can be written by the OEM at the memory
card’s attribute memory address space beginning at
address 00000H by using a format utility. The CIS ap-
pears at the beginning of the Card’s attribute memory
space and defines the low-level organization of data on
the PC Card. The “C” series cards contains a separate
512 byte EEPROM memory for the cards’ attribute
memory space. This allows all of the Flash memory to
be used for the common memory space.
Third party software solutions such as Microsoft’s
Flash File System (FFS), M-System’s True FFS, and
SCM’s SCM-FFS, enable AMD’s Flash Memory PC
Card to replicate the function of traditional disk-based
memory systems.
Widespread acceptance of the “C” series cards is as-
sured due to their compatibility with the 68-pin PCM-
