JEDEC presents new standards
JEDEC has finally passed the DDR333 standard, on the basis of which all manufacturers can finally refer during production. However, several manufacturers have already started production of DDR400, including Kingmax.
At the JEDEX conference in San Jose, California, JEDEC also presented its new roadmap for the DDR II standard. According to this, the DDR II modules are to be operated with clock rates of 400, 533 and 667 MHz with system memory, the previously planned frequency of 600 MHz has been canceled. For memory modules for graphics cards, frequencies of 800 and 1000 MHz are provided. The memory chips are operated with 1.8 volts and have a storage density of at least 512 Mbit. 200-, 220- and 240-pin FBGAs are used as housing forms. JEDEC intends to announce the final specifications for DDR II in September so that the first DDR II modules can come onto the market by the end of the year.
