Breakthrough in high density serial Flash memory

1 min read

Macronix International has announced what it claims to be the world's first 256Mbit serial Flash product.

The MX25L25635E is based on a 32bit addressing scheme and Macronix says that it has created a simple way to extend the serial Flash density beyond 128Mbit while supporting the existing 24bit addressing for backward compatibility. According to the company, the new product provides a small form factor, low pin count and reduces the overall system cost in applications such as networking, set top boxes and servers. Serial Flashes are traditionally based on a 24bit addressing protocol which caps the maximum density at 128Mbit. Macronix says it has addressed the need for greater densities to assist designers to store code and applications for more complex and feature rich products. Alan Niebel, ceo and founder of Web-Feet Research, said: "Macronix has enhanced its leadership position in serial Flash by being the first company to offer the highest density 256Mbit product in the market. The serial Flash market is the fastest growing NOR Flash segment increasing from $645million in 2009 and with the addition of the 256Mbit serial part it should reach $2,036m by 2014." The MX25L25635E, 256Mbit multi I/O serial Flash is sampling in October, with mass production scheduled for December 2009.
