Memory industry standards body JEDEC Solid State Technology Association has announced the publication of JESD216 SFDP for serial NOR flash.

The SFDP will allow serial flash manufacturers to embed a standard description of important device characteristics inside the flash chip.

Users can read the description and obtain critical information about the functional characteristics and capabilities of SFDP-compliant flash memory devices, which will enable user applications such as mobile phones, set-top boxes, HDTVs, PC/NB motherboards, or any system that needs to support multiple serial NOR flash device types, to configure themselves to handle various serial flash implementations, JEDEC said.

JESD216 provides a consistent method of describing the functional and feature capabilities of serial flash devices in a standard set of internal parameter tables, JEDEC indicated. These parameter tables can be interrogated by host system software to enable adjustments needed to accommodate divergent features from multiple vendors. In this way, SFDP offers more flexibility in vendor selection, reduces engineering resources for firmware upgrades, and shortens the time to bring products to market.

Macronix International said it has already embedded SFDP in its serial flash family products, and will gradually activate the feature from now on.

Macronix actively participated in the creation of the SFDP standard, the company indicated. Serial flash products are evolving with diverse feature sets, expanding from single I/O throughput to multiple I/O data throughput capability. Macronix added that it had been striving to unify and standardize the serial flash specification.

Macronix' SFDP-compliant flash memory devices are currently shipping to customers, the company noted
