NatSemi qualifying nanotech memory process
Cavendish Kinetics is working with National Semiconductor to qualify its Nanomech embedded non volatile memory technology for use on National’s key analogue and mixed signal processes.
The basic idea behind Nanomech is the use of an array of MEMs cantilevers to store information. Initially, the cantilever is open, but application of a small charge closes what is essentially a switch, thereby storing a bit. The process is comparable to eeprom, but is 100 times faster and uses 1000 times less power. It also offers high temperature resistance, making the technology potentially attractive in automotive ‘under the hood’ applications.
"The excellent operating characteristics of Cavendish Kinetics’ novel embedded non volatile memory makes it a key addition to our technology portfolio," said Mohan Yegnashankaran, senior vice president of worldwide technology development for National Semiconductor. “It can be easily combined with our current process technology options to enable higher performance signal path and power products.”
Nanomech technology is incorporated on the top metal layer of standard cmos and other processes. Since it works at native voltage, it saves silicon area and power.
Dennis Yost, Cavendish Kinetics’ ceo, said: “We appreciate National's vote of confidence in Nanomech and look forward to working closely with National to solve its embedded non volatile memory needs.”
