A method and circuit for implementing an enhanced static random access memory (SRAM) read and write performance ring oscillator, and a design structure on which the subject circuit resides are provided. A plurality of SRAM base blocks is connected together in a chain. Each of the plurality of SRAM base blocks includes a SRAM cell, such as an eight-transistor (8T) static random access memory (SRAM) cell, and a local evaluation block coupled to the SRAM cell. The SRAM cell includes independent left wordline input and right wordline input. The SRAM cell includes a read wordline connected high, and a true and complement write bitline pair connected low. In the local evaluation circuit, one input of a NAND gate receiving the read bitline input is connected high. A control signal is combined with an inverted feedback signal to start and stop the ring oscillator.
