Manufactured 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 approach to single-supply Flash memory cards. Data files and application programs can be stored on the D-Series cards. This allows OEM manufacturers of portable systems to eliminate the weight, high-power consumption 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 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 memory 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 memory 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.

The earlier C-Series Cards were based on the 4 MBit 5.0 Volt-only device, the Am29F040. s The D-Series Cards program faster than the CSeries Cards. This is due to faster byte write times and an optimized address unlock sequence for write operations. s The D-Series Cards are offered in higher densities. The D-Series Cards are available in densities of 4 MBytes, 8 MBytes, 20 MBytes, and 32 MBytes. The earlier C-Series Cards were available in densities of 1 MByte, 2 MBytes, 4 MBytes and 10 MBytes. The additional features that are supported in the new D-Series Cards include s The D-Series Cards support the RESET feature. This allows you to asynchronously RESET the Card into the read state. s The D-Series Cards also provide the RY/BY functionality. This feature provides a quick way of determining if the Card is busy doing a write or erase operation, or if it is in a position to undertake the next operation. s Availability of an additional Toggle bit (D2) to determine if the Card is in the Embedded Erase or Erase Suspend mode. s Programming operations can be executed in 8 µs pulses, down from the 16 µ s o n the C-Series Cards (typical). s Time out from the rising edge of the WE pulse for sector erase command reduced from 100 µs t o 50 µs. s The D-Series Cards offers a low power standby mode with fast recovery time to read. The typical standby current (ICCS) is
