Abstract
A method of generating a random number from an electronic circuit memory and/or a system with the electronic circuit memory. The memory comprises a block of ferroelectric two transistor, two capacitor (2T-2C), memory cells. The method comprises: (i) first, writing a predetermined programming pattern to the block cells in a one transistor, one-capacitor (1T-1C) mode, thusly writing, per cell, a same data state to both a first and second sub-cell of the cell; (ii) second, reading the cells in a 2T-2C mode to generate a random number comprising a random bit from each of the cells; (iii) third, restoring the random number into the cells in a 2T-2C mode, thusly writing, per cell, a complementary data state to both a first and second sub-cell of the cell, responsive to a respective random number bit; and fourth, imprinting the random number in each cell in the block.
