Pre-charge voltage generation circuit for a random memory and a random memory are provided. The pre-charge voltage generation circuit is configured to selectively provide a pre-charge voltage and includes: a voltage generation module, configured to generate a first voltage and a second voltage, wherein either of the first voltage and the second voltage serves as the pre-charge voltage, the first voltage is greater than the second voltage; a selection module, coupled to the voltage generation module, configured to select and output the second voltage as the common end voltage of the storage capacitor of the random memory in response to an operation command being a write command, and configured to select and output the first voltage as the common end voltage in response to the operation command being a read command.
