No, SRAM doesn't work that way. DRAM needs refreshing because it's made out of capacitors; if left alone, their charge will stay the same. Whereas SRAM is made of flip-flops; if the charge in an SRAM cell moves towards an intermediate state in between 0 and 1, it will naturally move back to 0 or 1 (whichever is closer) with no refreshing needed, by virtue of its structure.
