Improvements in or relating to EEPROMS

摘要: Semiconductor circuit provides an EEPROM programming charge pump (18), and includes a leakage current measuring device (12), plurality of interconnected mirrors, controlled oscillator (16) for providing power to such EEPROM. The sensor (12) generates nonlinearly related ambient temperature the semiconductor circuit, mirrors combining scaling (14) with constant provide composite altering frequency that each rise in about 8°K-10°K doubles. output is constrained accordingly (18) proportional ensuring only amount appropriate delivered, achieving high economy total utilization, as miniaturized, self-contained responder read/write transponder system resident on single integrated chip.
