Abstract
A bit line power supply apparatus including a bit line high voltage generator is provided. The bit line high voltage generator includes a first voltage generation circuit and a second voltage generation circuit. The first voltage generation circuit includes a first sensor and a first linear voltage regulator. The first sensor compares a first reference voltage with a bit line high voltage to generate a first sensing voltage according to a first control signal. The first linear regulator generates the bit line high voltage according the first sensing voltage. The second voltage generation circuit includes a second sensor and a switching voltage regulator. The second sensor compares the first reference voltage with the bit line high voltage to generate a second sensing voltage according to a second control signal. The switching regulator generates the bit line high voltage according the second sensing voltage.
