ONE-TIME PROGRAMMABLE MEMORY AND SYSTEM-ON CHIP INCLUDING ONE-TIME PROGRAMMABLE MEMORY

摘要

A one-time programmable (OTP) memory includes an OTP cell array including a plurality of OTP cells that each include a programming transistor configured to change irreversibly when programmed; a temperature compensation reference voltage generating unit configured to sense a temperature of the OTP cell memory and generate a reference voltage such that as the sensed temperature changes, the reference voltage generated by the temperature compensation reference voltage generating unit changes in a manner that is inversely proportional the change in the sensed temperature; and a temperature compensation operating voltage generating unit configured to receive the reference voltage to generate an operating voltage that is proportional to the reference voltage and is applied to the OTP cell array.
