No, ReadyBoost does not increase RAM. ReadyBoost is a feature in Windows that allows you to use a USB flash drive or SD card as a form of virtual memory, or "cache," to improve the performance of your computer. It works by using a portion of the flash drive's storage space to hold data that is frequently accessed by the system, which can help to speed up the performance of the computer. However, it does not add additional RAM to the system.
