An advanced 50-nanometer Floating Gate NOR Flash, or SPI NOR Flash, researched and developed by Wuhan Xinxin Semiconductor Manufacturing Co Ltd (XMC), went into mass production recently and promises big things, according to a June 5 report on the WeChat public account of the Optics Valley, where the company is based.
XMC is resident at the East Lake High-tech Development Zone, also known as Optics Valley of China, located in Wuhan, capital city of Central China's Hubei province.
A company spokesman said it took 18 months to achieve a breakthrough in related technologies and then move into mass production.
Currently, in international field of NOR Flash memory chips, the common technology is 65nm. The company's spokesman said the new generation of 50nm technology in XMC has approached the physical limit of this kind of chip.
He said the storage unit area and storage density had reached the advanced international level.
According to an XMC researcher, he and his colleagues believe the chip can achieve efficient memory access in continuous reading mode, which requires only 4.88-nanosecond instruction cycles to read 24-bits of addresses.
In addition, it can extend the battery life of portable devices by more than 1.5 times, enabling users to achieve better inventory management through a wide voltage function.
