What is max MEM% in top command?

HI,
When i use the top command in Linux I get the below values.

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

What is the maximum MEM% that will occur. I got once 303% . Is it possible to get such a high value.

Regards,
Ahamed.

see the man page of top
UNIX man pages : top ()

Maybe I'm blind, but I don't see that the manual you RTFMed explains why %MEM could possibly have a value higher than 100%. It doesn't even say if %MEM represents virtual or physical memory.
