Abstract
A dynamic voltage supply circuit of a nonvolatile memory device includes a voltage amplification/output circuit and a dynamic voltage output circuit. The voltage amplification/output circuit receives a first clock signal and a second clock signal to generate a dynamic supply voltage greater than a supply voltage while the first clock signal has a 'low' level. The dynamic voltage output circuit outputs the dynamic supply voltage while the first clock signal has a 'low' level and outputs a ground voltage while the first clock signal has a “high” level.
