Patent number: 11900995Abstract: Various implementations described herein are related to a method for accessing a bitcell in an array of bitcells with a wordline and a bitline. The method may perform a precharge operation on the bitline that precharges the bitline after a read cycle and before a write cycle. Also, the method may extend precharge time of the precharge operation between the read cycle and the write cycle, e.g., by modulating a wordline signal on the wordline with early cut-off of the wordline signal on the wordline during the read cycle.Type: GrantFiled: April 6, 2021Date of Patent: February 13, 2024Assignee: Arm LimitedInventors: Rajiv Kumar Sisodia, Andy Wangkun Chen, Sriram Thyagarajan, Yew Keong Chong, Ayush Kulshrestha, Munish Kumar
