Patent number: 11914515Abstract: A cache memory device is provided in the disclosure. The cache memory device includes a first AGC, a compression circuit, a second AGC, a virtual tag array, and a comparator circuit. The first AGC generates a virtual address based on a load instruction. The compression circuit obtains the higher part of the virtual address and generates a target hash value based on the higher part of the virtual address. The second AGC generates the lower part of the virtual address based on the load instruction. The virtual tag array obtains the lower part and selects a set of memory units. The comparator circuit compares the target hash value to a hash value stored in each memory unit of the set of memory units. When the comparator circuit generates the virtual tag miss signal, the comparator circuit transmits the virtual tag miss signal to the reservation station.Type: GrantFiled: October 20, 2022Date of Patent: February 27, 2024Assignee: SHANGHAI ZHAOXIN SEMICONDUCTOR CO., LTD.Inventors: Junjie Zhang, Mengchen Yang, Jing Qiao, Jianbin Wang
