Abstract
A programmable memorycomprises programmable data bit cells. A data word comprises a group of the programmable data bit cells. A method of configuring patch code in the memorycomprises identifying a first location (e.g. 0x1234) in the programmable memorywhere a patch is required; modifying a data word at the first location to a predetermined data value (e.g. 0xFFFF); writing patch code for the patch at a patch code location (e.g. 0xABCD); and storing the patch code location. The predetermined data value can be, or can map to, a value of an exception instruction of the processorwhich will cause the processorto read from a patch table. The programmable memorycan be a One Time Programmable (OTP) memory.
