Electronic device for manufacturing of semiconductor device and operating method of electronic device

Abstract

An operating method of a circuit design system which includes a processor and a memory includes reading, at the processor, a circuit layout of a flash memory device including a page buffer from the memory, initializing, at the processor, a value of a first parameter of at least one transistor of the page buffer and a value of a second parameter of at least one voltage applied to the page buffer, performing, at the processor, circuit simulation on the page buffer using the initialized first and second parameters, and calculating, at the processor, a reward based on a result of the circuit simulation. The processor is configured to perform, in response to the reward being not greater than a threshold value, a subsequent action. The subsequent action includes adjust the value of the first parameter of the at least one transistor and the value of the second parameter of the at least one voltage, and perform subsequent circuit simulation on the page buffer using the adjusted first and second parameters.
