Kilopass has introduced an improved version of its antifuse one-time-programmable (OTP). Called Gusto, it’s licensed as process-portable intellectual property (IP). It offers 4MB OTP, quadrupling the capacity of existing OTP memories. It’s large enough to store boot code and system firmware, rather than just code patches, configuration code, and trim settings for analog components. In addition, Kilopass claims Gusto reads memory two to four times faster, cuts active power consumption by an order of magnitude, and slashes current leakage in standby mode by a factor of 40.
