Abstract: A low-consumption TTL-CMOS input buffer stage includes a chain of inverters cascade connected between an input receiving electric signals at a TTL logic level and an output reproducing electric signals at a CMOS logic level, and powered between a first or supply voltage reference and a second or ground reference. Advantageously, the first inverter in the chain includes a means of selecting the delivery path to the stage according to an activate signal for a low-consumption operation mode. In essence, the first inverter of the buffer has two signal paths: one for normal operation and the other for low consumption operation.

Abstract: An equalization control circuit having an equalization signal generating stage having an enabling input receiving an address transition signal, a disabling input receiving a disabling signal, and an output generating an equalization control signal. An auxiliary line is supplied at one initial terminal (35a) with a biasing voltage correlated to the reading voltage supplied to the addressed array cell. An equalization filter is connected to the end terminal of the auxiliary line and generates the disabling signal when the voltage at the end terminal of the auxiliary line exceeds a preset threshold value.
