GENERAL DESCRIPTION
AMD’s 5.0 Volt-only Flash Memory PC Card provides
the highest system level performance for data and file
storage solutions to the portable PC market segment
and a wide range of embedded applications. Manufac-
tured with AMD’s Negative Gate Erase, 5.0 Volt-only
technology, the AMD 5.0 Volt-only Flash Memory
Cards are the most cost-effective and reliable ap-
proach to single-supply Flash memory cards. Data files
and application programs can be stored on the D-Se-
ries cards. This allows OEM manufacturers of portable
systems to eliminate the weight, high-power consump-
tion and reliability issues associated with
electro-mechanical disk-based systems. The D-Series
cards also allow today’s bulky and heavy battery packs
to be reduced in weight and size. AMD’s Flash Memory
PC Cards provide the most efficient method to transfer
useful work between different hardware platforms. The
enabling technology of the D-Series cards enhances
the productivity of mobile workers.
Widespread acceptance of the D-Series cards
is assured due to their compatibility with the
s Enhanced power management for standby
mode
— 1 µA typical standby current
— Standard access time from standby mode
s Separate attribute memory
s Automated write and erase operations increase
system write performance
— 64K byte memory sectors for faster automated
erase speed
— Typically 1 s per single memory sector erase
— Random address writes to previously erased
bytes (8 µs typical per byte)
s Total system integration solution
— Support from independent software and
hardware vendors
s Low insertion and removal force
— State-of-the-art connector allows for minimum
card insertion and removal effort
s Erase Suspend/Resume
— Supports reading or programming data to a
sector not being erased within the same device
s Support for RY/BY and RESET signals
68-pin PCMCIA/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 into the mem-
ory card’s attribute memory address space beginning
at address 00000H by using a format utility. The CIS
appears at the beginning of the Card’s attribute mem-
ory space and defines the low-level organization of
data on the PC Card. The D-Series cards contains a
separate 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 and
SystemSoft’s Flash File System (FFS2), SCM’s
SCM-FTL, and Datalight’s Cardtrick enable AMD’s
Flash Memory PC Card to replicate the function
of traditional disk-based memory systems.
