Abstract
Various implementations described herein are directed to an integrated circuit having a wordline driver coupled to a bitcell via a wordline. The wordline driver may include multiple transistors. The integrated circuit may include a read assist transistor coupled to the wordline between the wordline driver and the bitcell. Gates of the read assist transistor and at least one transistor of the multiple transistors may be coupled together. While activated, the read assist transistor may provide a read assist signal to the wordline when the wordline is selected and driven by the wordline driver.
Claims20
An integrated circuit, comprising:
- a wordline driver coupled to a bitcell via a wordline, wherein the wordline driver comprises multiple transistors;
- and
- a read assist transistor coupled to the wordline between the wordline driver and the bitcell, wherein gates of the read assist transistor and at least one transistor of the multiple transistors are coupled together, and wherein while activated, the read assist transistor provides a read assist signal to the wordline when the wordline is selected and driven by the wordline driver.
An integrated circuit, comprising:
- a wordline driver coupled to a bitcell via a wordline, wherein the wordline driver comprises a first p-type transistor and an n-type transistor;
- and
- a second p-type transistor coupled to the wordline between the wordline driver and the bitcell, wherein gates of the first p-type transistor and the second p-type transistor are coupled together, and wherein while activated, the second p-type transistor provides a read assist signal to the wordline when the wordline is selected and driven by the wordline driver.
A method for manufacturing an integrated circuit, the method comprising:
