Abstract
An OTP with ultra-low power read can be programmed with a minimum and a maximum program voltage. When programming within the range, the post-program OTP to pre-program resistance ratio can be larger than N, where N>50, so that more sensing techniques, such as single-end sensing, can be used to reduce read current. At least one of the OTP cells can be coupled to a common bitline, which can be further coupled to a first supply voltage lines via a plurality of datalines. The resistance in the at least one OTP cell can be evaluated by strobing at least one comparator output of the discharging bitline/dataline.
