180nm OTP Non Volatile Memory for Standard CMOS Logic Process
NSCore's PermSRAM(R) is the only embedded CMOS, one time programmable (OTP), non-volatile RAM IP of its kind, utilizing the 'hot carrier effect' to trap charge in the sidewall spacer of the gate. PermSRAM provides the benefits of Embedded Flash without the additional process cost in a secure, on-chip memory configuration qualified under automotive conditions. PermSRAM IP is available for mainstream foundries as well as several undisclosed Japanese IDM's. Please contact us to learn how our NVM IP can be used to replace EEPROM or ROM combined with on-chip SRAM for applications requiring extreme security such as HDMI or requiring analog trimming such as LCD controllers.
