<p>Control circuitry and a method for generating an accurate boosted wordline voltage for selected memory core cells in a semiconductor memory device during a Read mode of operation is provided. Memory core transistors are provided which have their conduction path being coupled between a power supply voltage and a ground potential. Differential amplifier circuitry (201a, 201b) is responsive to a boost signal and a reference voltage for generating a select wordline voltage. The select wordline voltage is decreased when the wordline voltage is higher than a desired voltage and is increased when the wordline voltage is lower than the desired voltage. The control gates of the memory core transistors are responsive to the select wordline voltage.</p> |
