Cache and main memory will lose their contents when the power is off. They are Volatile.
Volatile memory is computer storage that only maintains its data while the device is powered. Most RAM (random access memory) used for primary storage in personal computers is volatile memory. ... Volatile memory contrasts with non-volatile memory, which does not lose content when power is lost.
Volatile memory, in contrast to non-volatile memory, is computer memory that requires power to maintain the stored information; it retains its contents while powered on but when the power is interrupted, the stored data is quickly lost. ... Most of the general-purpose random-access memory (RAM) is volatile.
If you are referring to processor caches, yes they are volatile. Today, the most common technology to make processor caches is Static RAM (SRAM). SRAM is really fast, but the cell size is relatively large, making it a good match for processor caches, but not for main memory.
