14 DAY TRIAL // The Koreans from Samsung have announced the availability of the OneNAND Flash software, called eXtended sector remapper (XSR), a solution which optimizes the functionality of OneNAND memory devices used for 3G cell phones, mobile gaming systems and digital cameras. The software simplifies the integration of OneNAND flash into these digital devices.
Until now, five cell phone optimization solutions have been developed, each of them dedicated to a specific domain; three of them are based on the XSR software developed by Samsung. The PocketStore II solution optimizes the OneNAND flash memory of the Microsoft Mobile environments.
The UniStoreII solution is used together with Symbian and TFS4 (Transactional File System 4) and incorporates the XSR software and a Flash file system in the same package for RTOS (Real Time Operating Systems). Moreover, Samsung is offering a software called RFS (Robust File System) for the Linux environments and the software TFS4-Light specifically designed for MP3 players which need a small amount of memory.
The XSR technology from Samsung, designed to provide OneNAND Flash memory for every mobile device that has an operating system, is offering a 30MB/sec reading speed and can write information with 9 MB/sec. In the same time, it simplifies the design process of multimedia mobile systems that have a low power consumption, high performances and are cheap.
The OneNAND memory includes NAND Flash, SRAM and IC logic memory in a single chip and is the only solution of this kind that communicates with NOR Flash memory. An important quality of this solution is the small amount of data lost in case of a power shortage.
