Semiconductor apparatus having transfer circuit transferring high voltage

摘要

A semiconductor apparatus includes a voltage supply circuit suitable for outputting a high voltage, a transfer circuit coupled between the voltage supply circuit and a peripheral circuit and suitable for transferring the high voltage to the peripheral circuit and a transfer control circuit suitable for outputting a transfer control signal to the transfer circuit to control the transfer of the high voltage to the peripheral circuit, wherein the transfer control circuit outputs the transfer control signal having a first positive voltage level to a gate of a transistor included in the transfer circuit when the voltage supply circuit outputs the high voltage to the transfer circuit.

1. A semiconductor apparatus, comprising:
a voltage supply circuit configured to output a high voltage to global line of a non-selected memory block; a transfer circuit configured to be coupled between the global line of the non-selected memory block and local line of the non-selected memory block and to transfer the high voltage to the local line of the non-selected memory block; and a transfer control circuit configured to output a transfer control signal to the transfer circuit for controlling transfer of the high voltage to the local lines of the non-selected memory block, wherein the transfer circuit include a pass transistors in which the high voltage is supplied to a drain of the pass transistor and the transfer control signal is supplied to a gate of the pass transistor, the transfer control signal has a first positive voltage level which is lower than a pass voltage supplied to a selected memory block when a program operation is performed, and wherein the transfer control signal has a ground level when a read operation or an erase operation is performed.
