<p>PURPOSE:To stabilize the operation of a memory, etc., by integrating a solid- state electrolyte battery for a back bias power source on a chip and supplying a stable back bias voltage. CONSTITUTION:On the chip of a memory package 3 which has terminals VCC and VSS for an external power souce and a dynamic memory circuit 4, etc., the solid-state electrolyte battery 5 with small capacity, etc., is integrated together with a charging circuit 7 which operates by the external power source. This battery 5 operates as a stable back bias power source and even during power-up operation, the oscillating circuit of the circuit 4 oscillates securely through a transistor with a negative threshold voltage, so that the memory operates stably.</p> |
