Abstract:
Technologies are generally described for partial programming of memory having physically unclonable functions for secure data storage. In some examples, a sender that wishes to securely send data to a recipient using a physical memory may measure a program threshold average and a program threshold variation for bits in the memory and group the bits into different bins based on the measured average and variation. The sender may partially program the data to a set of bits selected from one or more of the bins by applying partial program pulses to the bits based on the program threshold average and the program threshold variation. The sender may then provide the partially-programmed memory to the recipient. The recipient may then partially program the received memory based on the program threshold average and the program threshold variation to recover the programmed data.
