Title:
RRAM VOLTAGE GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/155322
Kind Code:
A1
Abstract:
An RRAM voltage generation system comprises a charge pump (12), a square-wave oscillator (13), a linear voltage regulator (14), a power-on control circuit (15), and a voltage and current reference source (11). The charge pump (12) is used for raising a voltage of an external power source and providing a power source to another sub-circuit. The square-wave oscillator (13) is used for providing a clock signal, and an output end of the square-wave oscillator (13) is connected to a clock signal input end of the charge pump (12). The linear voltage regulator (14) is used for providing a driving voltage for the operation of a storage unit, and an output end of the linear voltage regulator (14) is sequentially connected to a row and column decoder (2) and a storage unit array (3). The linear voltage regulator (14) is also connected to an external power source VCC and a charge pump (12) output power source VPP. The power-on control circuit (15) is used for providing a power-on reset signal to a system, and also controlling the sequential start of the charge pump (12), the square-wave oscillator (13) and the linear voltage regulator (14). The voltage and current reference source (11) is used for providing a reference voltage and a reference current to the charge pump (12), the square-wave oscillator (13), the linear voltage regulator (14) and the power-on control circuit (15). Both an external power source and the charge pump (12) of a double-branch structure with good technological compatibility are used to separately supply power to the linear voltage regulator (14), and multiple bytes are supported.
