Hitachi, Ltd. ( TSE: 6501 ) today announced 512-Mbit AND-type flash memory HN29V51211T
and 1-Gbit AND-type flash memory HN29V102414T employing Hitachi's Double Density
Package(DDP) for use as a hard disk replacement in communication and industrial
equipment and the largest-capacity flash card in digital still cameras and portable
music players. By using this 512-Mbit device, the industry's largest-capacity 2-Gbyte
PC-ATA card HB28B2000A6 / 128-Mbyte MultiMediaCard(TM)*1 HB28B128MM1 are also released.
Sample shipment of these 4 products will start from the end of 2000 in Japan.
A 512-Mbit AND-type flash memory achieved a small chip size and low power consumption
by using 0.18 ¦Ìm process and adopts the Multi Level Cell technology*2, and provides
a large-capacity and low power consumption of flash card.
Flash cards have become popular as the mass storage medium for all types of portable
equipment, from digital still cameras and portable music players to hand-held PCs,
and we expect demand for flash cards that provide security functions to increase due
to the implementation of music distribution services and e-commerce services for
mobile phones. Furthermore, flash memory holds promise for communication and industrial
areas that had previously used low-capacity hard disks, since flash memory has lower
system maintenance costs than hard disks, and has superior characteristics in terms of
low power and resistance to mechanical vibration. The replacement from low-capacity
hard disks to silicon disks and from low-capacity hard disks to PC-ATA card in new
system design started.
To respond to the needs for increased capacity in these and other applications,
Hitachi has developed and is now releasing the 512-Mbit/1-Gbit large-capacity flash
memory, 2-Gbyte PC-ATA card, and 128-Mbyte MultiMediaCard.
1. 512-Mbit AND-type flash memory "HN29V51211T"
A 512-Mbit AND-type flash memory is jointly designed with Mitsubishi Electric
Corporation. This device is fabricated in a 0.18 ¦Ìm process and takes full advantage of
Multi Level Cell technology and know-how fostered in the development of Hitachi's 256-
Mbit product to implement the large storage capacity of 512-Mbits in a small chip size
less than that of conventional 256-Mbit flash memory. This device also achieves a read
current consumption of 2 mA (typical) in the range 2.7 to 3.6 V for low power
consumption of portable equipment.
2. 1-Gbit AND-type flash memory "HN29V102414T"
A 1-Gbit product achieves the large capacity by using Hitachi's Double Density
Package (DDP) containing two stacked 512-Mbit AND-type flash memory chips, and
thus creates a 1-Gbit flash memory in the same 48-pin TSOP type I package used for
conventinal 256- Mbit / 512-Mbit flash memory products.
3. 2-Gbyte PC-ATA card "HB28B2000A6"
This product mounts sixteen of the HN29V102414T 1-Gbit AND-type flash memory
products to achieve the industry's largest-capacity 2-Gbyte PC-ATA card which is the
twice strage capacity of exist 1-Gbyte PC-ATA card. The same Hitachi AND-type flash
memory controller as used with previous products implements interleaved operation of
multiple chips, enabling a maximum programming speed of 2-Mbyte/second to be
achieved.
4. 128-Mbyte MultiMediaCard(TM) "HB28B128MM1"
A MultiMediaCard consists of flash memory and a controller. This new product
incorporates two 512-Mbit flash memory chips and a cell-based IC with a SuperH(TM)*3
RISC microcomputer as the CPU core and can store 2 hours of music data when common
compression technology such as MP3 (MPEG-1/Audio Layer3) is used.
MultiMediaCard standardization is undertaken by the MultiMediaCard Association, and
specifications are available to members in System Spec form. These new products
conform to System Spec Version 2.11. As with the 16-/32-/64-Mbyte product, the
overall product specifications have been formulated in collaboration with Infineon
Technologies AG.
These new products achieve a read speed of 14-Mbit per second and a write speed of
5- Mbit per second, among the fastest in the industry, while operating on a low
voltage of 2.7 to 3.6 V. As interface of card, both MultiMediaCard mode and SPI
mode are supported, allowing the user to select the most appropriate interface
method for a specific product system design.
Support tools for use when designing a system using MultiMediaCards are available
from third-party suppliers, including driver, file manager, and other software*4,
hardware such as an H8S microcomputer-based development platform, and also a
dedicated MultiMediaCard protocol analyzer*5 as analytical tools.

2. Multi Level Cell technology: A technology that is applied to large-capacity
flash memory and is effective at reducing chip size. In normal memories, two
threshold levels, corresponding to data values of 0 and 1, are used. However,
in Multi Level Cell flash memory, four and more values are defined, corresponding
to data values of 00, 01, 10, and 11. Since this 512-Mbit product can define
four values, a single memory cell can perform the function of two memory cells
in earlier technologies.

5. An H8S microcomputer-based development platform and dedicated MultiMediaCard
protocol analyzer are marketed by KOKUSAI ELECTRIC ALPHA Co.,LTD.
