[0030] As mentioned in the background art section, the voltage maintenance circuit in the prior art memory is faced with the problem that low power consumption characteristics and easy-to-control output voltage characteristics cannot be compromised.
[0031] The inventor of this application analyzed the prior art. figure 1 It is a circuit diagram of an existing voltage maintenance circuit for memory; the memory can be SRAM, because the data is not lost after SRAM is powered on, and the data stored in it can be saved without refreshing the circuit, which is required in SRAM A voltage is maintained to ensure that the internal data is not lost. Such as figure 1 As shown, the voltage maintenance circuit 100 for the memory may include a bandgap reference source (Bandgap) 10, a voltage comparator 20, a voltage divider circuit composed of a resistor R1 and a resistor R2, and a PMOS switch tube P1, wherein the voltage divider The circuit has a voltage dividing node A, and the voltage out...
