The new 64Mbit RAM is designed for mobile phones and wireless Internet devices. According to NEC it features reading speeds of 65 nanoseconds per address and 18 nanoseconds per page.
As the volume of data transferred wirelessly over the internet has grown, various high-volume DRAM and SRAM products have been developed. However, DRAM power consumption is high, and SRAM gets expensive at over 16Mbits.
To address these problems, NEC unveiled the first generation of low-power consuming mobile specified RAM of 16Mbits in 2000 and 32Mbits in 2001. The 64Mbit RAM chip is the latest in this family.
The sample price is 3,000 yen (£15) per chip. The company plans to start mass production in May this year.
