Abstract |
AB |
[EN] A semiconductor memory device including an array of memory cells (MC) formed on a substrate each realized from a load element and thyristor that define a switchable current path whose state represents a volatile bit value stored by the MC. At least one word line corresponding to a respective row of the array is formed on the substrate and coupled to MC current paths for the corresponding row. Bit lines corresponding to respective columns of the array are formed on the substrate and can be coupled to a modulation doped QW interface of the MC thyristors for the corresponding column. Circuitry is configured to apply electrical signal to the word line(s) in order to generate current that programs phase change material of the MC load elements into one of a high or low resistive state according to state of the current path of the MCs for non-volatile backup and restore purposes. |
