Publication number: 20250060777Abstract: A memory device is provided and includes a memory array, first to second latch circuits and a gating circuit. Read and write operations are triggered by first and second edges of an internal clock signal respectively. The first latch circuit generates a first output signal in response to an input signal and a first latch clock signal, a first edge of the first latch clock signal generated based on the first edge of the internal clock signal. The second latch circuit generates a second output signal in response to the first output signal and a second latch clock signal, a first edge of the second latch clock signal being between first and second edges of the first latch clock signal. The gating circuit generates, in response to the second output signal and a gating clock generated, a third output signal to the memory array.Type: ApplicationFiled: August 28, 2023Publication date: February 20, 2025Applicants: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD., TSMC Nanjing Company LimitedInventors: Ming-Hung CHANG, Luping KONG, Jun XIE, Ching-Wei WU

Publication number: 20250006255Abstract: A memory circuit includes a control circuit coupled to the word line driver circuit. The control circuit is configured to delay a leading or falling edge of a word line signal in response to at least a first clock signal. The control circuit includes a first clock circuit configured to generate a second clock signal in response to a first reset signal and a clock signal, and an adjustable delay circuit configured to adjust a delay between the second and third clock signal in response to the second clock signal and an enable signal. The third clock signal is a delayed version of the second clock signal. An amount of the delay between the second and third clock signal is based on a voltage difference between a first supply voltage having a first swing, and a second supply voltage having a second swing.Type: ApplicationFiled: July 26, 2023Publication date: January 2, 2025Inventors: Luping KONG, Chia-Cheng CHEN, Ching-Wei WU, Jun XIE

Patent number: 12183432Abstract: A circuit includes a series of a first latch circuit, selection circuit, second latch circuit, and pre-decoder. A control circuit, based on a clock signal, outputs control signals to the selection circuit and first and second latch circuits, and, to the pre-decoder, a pulse signal including a first pulse during a first portion of a clock period in response to a read enable signal having a first logical state, and a second pulse during a second portion of the clock period in response to a write enable signal having the first logical state. Based on the control signals, the selection circuit and first and second latch circuits output read and write addresses to the pre-decoder during the respective first and second clock period portions, and the pre-decoder outputs a partially decoded address in response to each of the read address and first pulse, and the write address and second pulse.Type: GrantFiled: July 18, 2023Date of Patent: December 31, 2024Assignees: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD., TSMC CHINA COMPANY, LIMITED, TSMC NANJING COMPANY, LIMITEDInventors: XiuLi Yang, Ching-Wei Wu, He-Zhou Wan, Kuan Cheng, Luping Kong
