 32GB SDHC memory card technology : Staktek Holdings, Inc., a market-leading provider of intellectual property and services for next-generation module technologies, announced a new Secure Digital High-Capacity (SDHC) memory card technology that will double the typical number of Flash devices in the card, enabling the highest-capacity SDHC storage cards. The capacity enabled by Staktek’s SDHC memory card technology will reach 32GB per card with the fall delivery of next-generation, multi-level cell (MLC) Flash memory devices. SDHC memory cards are removable Flash storage cards used in a large variety of consumer electronics devices, such as digital still cameras, digital video cameras and personal media players.

For digital video cameras, including high-definition digital video cameras, increasing the card’s capacity directly translates into longer video recording times. “We are excited to enable a higher capacity for removable digital storage media in the SDHC card format,” said Ulrich Hansen, senior director of marketing for Staktek. “With the falling prices of flash components, these high-capacity memory cards are attractive not only to digital media professionals working with very large media files, but also to consumers looking to conveniently capture their memories in high-quality digital media form on a single, long-lasting card.”

To achieve the high-card capacity, Staktek is applying its broad IP portfolio and assembly know-how for high-density memory and module solutions to the SD card form factor. As a result, four fully tested, industry-standard, multi-die, thin small-outline package (TSOP) devices can be accommodated in the card while maintaining a maximum card thickness of only 2.25mm as required by the SD specification. The conventional SD card form factor only accommodates two standard height TSOP devices.
Staktek SDHC memory card - Dual channel flash controller
Staktek is utilizing a dual-channel Flash controller that supports both MLC and SLC NAND Flash in the current Staktek SDHC card reference design to deliver excellent card read/write performance. The card technology is compatible with SDHC controllers from various manufacturers, as well as JEDEC-compliant Flash TSOP devices, giving the card maker important flexibility in component sourcing. The Staktek SDHC memory card technology is fully compliant with the SDHC specification (SD Specification Version 2.0). Engineering samples of this card are available now, and the technology is available for licensing. Staktek will be showing its SDHC card technology at Computex 2007 in Taipei, Taiwan from June 6 - 8. Companies interested in learning more about this technology can contact Staktek.
