Abstract
A method and apparatus for generating a chip select signal include: sampling an external control signal to obtain a first and a second sampling signals; inputting the first sampling signal into a first vector file to generate a power supply control signal; inputting the second sampling signal into a second vector file to generate a chip select control signal; generating a chip select signal based on the power supply control signal and the chip select control signal, which include a high potential, a low potential and a high resistance state, the high potential voltages of the power supply control signal and the chip select control signal are different, and the low potential voltages of the power supply control signal and the chip select control signal are different. The disclosure realizes four different potentials for the chip select signals by applying two vector files.
