Title: Latching type level shift circuit
Inventor: UMEZAWA AKIRA
IPC: G11C16/06
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of leakage currents in a level shift circuit at the time of generating negative potential. SOLUTION: Logic circuits 19, 20, 21 make one of MOS transistors MN1, MN2 of a level shifter to an on-state, based on an operation mode and an address signals. Potentials of output terminals (a), (b) of the level shifter are guided to latching circuits INV1, INV2 via MOS transistors MP1, MP2. Internal power source potentials VROW', VBB are supplied to the latching circuits INV1, INV2. At erasing operation and verification (at read-out), VBB becomes a negative potential, either of nodes A, B becomes a negative potential. At this time, a leakage current will not be caused, since MOS transistors MP1, MP2 are kept at off state.

Title: Power source control device
Inventor: TASHIRO KEI
IPC: G05F1/56
Filed: 1997-12-29
Abstract: PROBLEM TO BE SOLVED: To suppress the wasteful power consumption and omit a smoothing circuit by generating a pulse width modulation signal changed in modulation degree according to a comparative value obtained by arithmetically processing the voltage of a battery power source with a reference voltage by arithmetic processing, and controlling a current switching means between a lighting load and the battery power source. SOLUTION: A one-chip type microcomputer 7 controls the pulse width modulation degree from a data obtained by dividing an input voltage data Vin by potential dividing resistors 13, 15 and a rated voltage Vu of reference voltage according to an arithmetic program stored in a ROM, and switches a drive element 11 by a rectangular wave signal modulated by a Duty (the ON rate per repeat period of the rectangular wave signal) satisfying the arithmetic expression so that a lighting bulb 5 consumes an average power PL. Since the flicker can be made inconspicuous by setting the frequency of the repeat period of the Duty high to drive the lighting bulb 5 with a high frequency switching signal, it is not required to provide a smoothing circuit between a switching element 9 and the lighting bulb 5.
