Low-power consumption and low-voltage operation PLA (L/sup 2/-PLA) using 1.2 mu m double poly-silicon CMOS E/sup 2/PROM technology

By using a unique CMOS E/sup 2/PROM technology, a novel field PLA (programmable logic array) has been developed. Owing to very low power consumption and low-voltage operation the PLA (L/sup 2/-PLA) is suitable for most consumer usage. To achieve this performance a soft-write free E/sup 2/PROM, a new low-power sense amplifier and an input transition detector (ITD) are used. L/sup 2/-PLA can operate in a wide range of supply voltage (1.0 V to 6.0 V) and consumes only 8 mA and 1 MHz (5 V supply voltage). Moreover, it has a standby mode in which the current consumption is extremely low (below 1 mu A).<>
