Abstract
A suspend-to-RAM controlling circuit includes a RAM (random access memory) controller, a logic circuit and at least one RAM module. The RAM controller has a controlling pin connected to the logic circuit. Each of the RAM modules has a first enable pin and a second enable pin connected to output pins of the logic circuit. The RAM module is driven to the STR (suspend-to-RAM) state after receiving an STR signal from the logic circuit. Therefore, the RAM controller can provide STR signals to a plurality of RAM modules by only one controlling pin in incorporation with the logic circuit.
