    摘要: A memory device including a memory array with a plurality of memory macros, a power supplying circuit, and a controller is provided. The power supplying circuit is coupled to the memory array. The controller is coupled to the memory array. The power supplying circuit is configured to provide power to perform write operations to a number of the memory macros at the same time. The number of the memory macros for the write operations performed at the same time is not higher than a maximum number of the memory macros. The controller obtains the maximum number of the memory macros for the write operations performed at the same time by the power supplying circuit. The controller re-arranges a schedule for a sequence of the write operations of the memory macros to generate a re-arranged schedule. The maximum number is taken as a threshold value. In the re-arranged schedule, a number of part of the memory macros for the write operations performed at the same time is equal to or less then the threshold value.

    摘要: The disclosed MTJ read circuits include a current steering element coupled to the read path. At a first node of the current steering element, a proportionally larger current is maintained to meet the requirements of a reliable voltage or current sensing. At a second node of the current steering element, a proportionally smaller current is maintained, which passes through the MTJ structure. The current at the first node is proportional to the current at the second node such that sensing the current at the first node infers the current at the second node, which is affected by the MTJ resistance value.

    摘要: An integrated circuit and an operating method thereof are provided. The integrated circuit includes memory cells, at least one first word line, second word lines, bit lines and write-assist bit lines. The at least one first word line is electrically connected to at least one row of the memory cells. The second word lines are electrically connected to other rows of the memory cells. Two bit lines are located between a column of the memory cells and two write-assist bit lines. The bit lines and the write-assist bit lines are configured to be electrically disconnected with each other when at least one of the memory cells electrically connected with the at least one first word line is configured to be written, and electrically connected with each other when at least one of the memory cells electrically connected to the second word lines is configured to be written.

    摘要: A memory device and a manufacturing method thereof are provided. The memory device includes a transistor, a first embedded insulating structure and a second embedded insulating structure. The transistor is formed on a substrate, and includes a gate structure, channel structures, a source electrode and a drain electrode. The channel structures penetrate through the gate structure, and are in contact with the source and drain electrodes. The first and second embedded insulating structures are disposed in the substrate, and overlapped with the source and drain electrodes. The first and second embedded insulating structures are laterally spaced apart from each other by a portion of the substrate lying under the gate structure.
