Patent ID: 8199600

Claim:
A microchip, comprising: a plurality of memory core blocks, and a voltage generator for a peripheral circuit, the voltage generator comprising: a single voltage supplier, included on the microchip, configured to supply a peripheral circuit voltage on an output having a voltage level maintained at a reference voltage level, the peripheral circuit voltage outputted in response to a driving signal, wherein the single voltage supplier includes a single inverter with an input connected to a driving signal; and a plurality of voltage level compensators configured to increase the voltage level of the peripheral circuit voltage in response to a column path command, wherein the plurality of voltage level compensators are connected in parallel to the single voltage supplier output, wherein each of the plurality of voltage level compensators comprise a driving unit driving the terminal connected to the peripheral circuit voltage with an external power supply voltage and a control unit generating a driving control signal in response to the column path command and a deep power down mode signal to control the driving unit wherein the plurality of voltage level compensators increase the voltage level of the peripheral circuit voltage during a read or write operation, and wherein the increased peripheral circuit voltage is used by the read and write operations of the peripheral circuit.
