摘要:
A semiconductor memory device including an address decode signal transmission circuit comprising address buffers; a predecoder; address buses provided before a main decode; a transmission circuit for outputting predecoded signals to the address buses while limiting amplitude thereof; and a receiving circuit provided before the main decoder for differentially amplifying signals from the address buses, wherein the memory cell array is divided into a plural number of sub-blocks and power can be selectively supplied to at least one of the sub-blocks.
摘要:
First and second gate-controlled switches are connected analogously to a Darlington transistor pair with a slow-response diode connected to delay application of a turn-off signal to the second gate-controlled switch until the first gate-controlled switch is fully turned OFF. The Darlington-type connection reduces a drive current required from a driving source to maintain the second gate-controlled switch fully ON for passing a load current therethrough.

摘要:
A semiconductor device including a substrate of semiconductor material having charge carriers of one conductivity type and a main region of opposite conductivity type. A ring of said opposite conductivity type is disposed around the main region and an auxiliary region of said opposite conductivity type is disposed on the opposite surface of the substrate. The said rings and the said auxiliary region are spaced from the main region by distances that permit the depletion region of the main region to reach the ring and the auxiliary region when the main region is reversed biased with respect to the substrate.
