To answer this question adequately, one must understand that information (on "computer chips", such as RAM, anyways) is kept using electrical charges, which are usually held in place by a battery of some sort. RAM does not have a battery, so it can only keep information until you turn off and/or unplug the computer. Also, since RAM is somewhat limited in size, it can only keep information until it is overwritten with new information. So if you do not turn off your computer, the time which it takes for the information on RAM to be overwritten (removed) will depend on A:the time you leave your computer on,
B:your operating system (and the amount of background activity associated with it)
C:how much stuff you do on your computer in any given time,
and
D: the amount of RAM you have in your computer.
until the computer shuts off then it goes back to the hard drive
ram will maintaian memory untill you turn your computer off
Some is stored in ROM; most of the information is typically stored on the hard disk, from where it is loaded into RAM.

Static RAM
Permanant information is stored in hard drives, usb drives, cds, dvds and the temporary information is stored in RAM (Random Access Memory).
Your computer erases the RAM when it is shut down.
Swap
Information stored in RAM can be accessed far faster than information stored in ROM. Thus, a computer might store its boot-up instructions in ROM, but store program files in RAM after initial boot-up.
CMOC RAM and ROM
It saves temporarily in the RAM, and when you save any information it goes to HDD.
the ram memory and the kernel cacheRAM
RAM requires a constant voltage to retain information. So by turning the PC off, all data in the RAM is lost.
