It is a simple utility to display the amount of RAM used by the terminal.

Additionally, the terminal version, the amount of memory that the terminal can theoretically occupy, and the total amount of memory available to the terminal are displayed.

For the x64 version of the terminal, the amount of theoretically available memory is 128 TB, while the actual amount of memory that will be used depends on the amount of physical and virtual memory available to the system (it is impossible to calculate this value).
