Patent ID: 11869573
Assignee: CHANGXIN MEMORY TECHNOLOGIES, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 15:
16. A semiconductor memory comprising:
a memory chip comprising at least a storage array; and
a voltage regulation unit comprising at least an operational amplifier, wherein the voltage regulation unit is configured to convert an external input first voltage into a second voltage to be provided to a word line driver circuit associated with the memory chip, wherein the external input first voltage is greater than the second voltage, wherein the voltage regulation unit further comprises a first resistor and a second resistor, wherein:
one end of the first resistor is coupled to the external input first voltage and the other end of the first resistor is coupled to one end of the second resistor;
the other end of the second resistor is coupled to a ground;
an electrical connection point formed between the first resistor and the second resistor is coupled to a positive input end of the operational amplifier;
a negative input end of the operational amplifier is coupled to an output end of the operational amplifier and outputs the second voltage; and
a supply end of the operational amplifier is coupled to the external input first voltage.
