Abstract: A system for N-gram classification in a field of interest via hyperdimensional computing includes an associative memory array and a controller. The associative memory array stores hyperdimensional vectors in rows of the array. The hyperdimensional vectors represent symbols in the field of interest and the array includes bit-line processors along portions of bit-lines of the array. The controller activates rows of the array to perform XNOR, permute, and add operations on the hyperdimensional vectors with the bit-line processors, to encode N-grams, having N symbols therein, to generate fingerprints of a portion of the field of interest from the N-grams, to store the fingerprints within the associative memory array, and to match an input sequence to one of the stored fingerprints.

Abstract: A system to generate true random numbers includes a RAM array, a null-read controller and a hash generator. The RAM array has memory cells and a sense amplifier. The memory cells store data therein, the cells are connected in rows to word lines and in columns to pairs of bit lines, and the sense amplifier senses a differential input signal. The null-read controller implements a null-read operation by the sense amplifier of a portion of the RAM array.
