Abstract
In accordance with an embodiment of the present invention, a semiconductor memory device includes an array of thyristor-based memory formed in a silicon-on-insulator (SOI) supporting substrate. A portion of the supporting structure of the SOI substrate has a density of dopants sufficient to assist delivery of a bias to the backside of an insulating layer beneath a thyristor of the thyristor-based semiconductor memory. By enabling biasing of the substrate at the backside of the insulating layer beneath the thyristor, a back-gate control is available for controlling or compensating the gain of a component bipolar device of the thyristor with respect to temperature.
