| L International Announces microPuRAM Technology L International Computers has unleashed the design of its microPuRAM Solid State Storage Technology for ultra-portable media and communications devices. Available in L's proprietary interface design based on the Compact Flash protocol, with initial sizes of up to 32GB per volume in Quad performance micro-raid 0 array configurations, L's new microPuRAM storage devices are high performing micro storage cards designed around ultra-fast high-bandwidth FlashRAM microchips targeting media devices, handhelds, PDAs, digital cameras and any ultra-portable hardware avid for desktop-like storage performance with ultra-low power consumption. Capable of blazing fast real-world internal read/write speeds, L's new microPuRAM memory cards are about the thickness of a credit card with 1/2 the length, and comprised of 4 independent memory chips in a quad-raid array configuration. By combining its expertise in Flash RAM designs and raid array configurations, L's design makes use of mass produced high-performance OEM memory chips and combines them in a small-form factor in packages of 4 raid interconnections, producing a storage solution ahead of the competition as future proof solution to any single chip memory card design. To ensure complete data integrity, L's microPuRAM Technology utilizes a proprietary Interleaved Reed-Solomon Error Correction Code (RS ECC) which is optimized for use with Flash memory. The RS-ECC code delivers an accuracy of a probability of less than 10-30 undetected data errors. It corrects up to six random byte errors per 528-byte blocks and detects burst errors up to nine bytes long. Additionally with its proper decoding algorithm, it will NEVER miscorrect three random byte errors as it will only miscorrect less than 0.1% of the time for errors greater than 9 bytes out of 528 bytes. A configurable ECC Threshold implements block memory remapping when the number of correctable errors for that block reaches a user configurable threshold value. Tuning this parameter minimizes the frequency of remapping blocks that exhibit a correctable error count less than the threshold. It also reduces the probability that certain blocks having correctable errors greater than the threshold will turn into blocks with uncorrectable errors. discuss the article write your comments about the article :: © 2006 Computing News :: home page |
