    Abstract: A semiconductor circuit and an operating method for the same are provided. The method includes the following steps. A memory circuit is operated during a first timing to obtain a first memory state signal S1. The memory circuit is operated during a second timing after the first timing to obtain a second memory state signal S2. A difference between the first memory state signal S1 and the second memory state signal S2 is calculated to obtain a state difference signal SD. A calculating is performed to obtain an un-compensated output data signal OD relative with an input data signal ID and the second memory state signal S2. The state difference signal SD and the un-compensated output data signal OD are calculated to obtain a compensated output data signal OD′.

    Abstract: A memory operating method and a memory operating device are provided. The memory operating method includes the following steps. A first stepping loop is performed. A second stepping loop is performed. In the first stepping loop, a first control voltage applied to a first control line is increased from a first initial value to a first final value which is larger than the first initial value, and a second control voltage applied to a second control line is fixed at a second initial value. In the second stepping loop, the first control voltage applied to the first control line is fixed at a fixing value, and the second control voltage applied to the second control line is increased from an intermediate value to a second final value which is larger than the second initial value.

    Abstract: An in-memory computation device and computation method are provided. The in-memory computation device, including a memory cell array, an input buffer, and a sense amplifier, is provided. The memory cell array includes a memory cell block. The memory cell block corresponds to at least one word line, and stores multiple weight values. Memory cells on the memory cell block respectively store multiple bits of each weight value. The input buffer is coupled to multiple bit lines, and respectively transmits multiple input signals to the bit lines. The memory cell array performs a multiply-add operation on the input signals and the weight values to generate multiple first operation results corresponding to multiple bit orders. The sense amplifier adds the first operation results to generate a second operation result according to the bit orders corresponding to the first operation results.

    Abstract: An in-memory computing device includes a plurality of synaptic layers including a first type of synaptic layer and a second type of synaptic layer. The first type of synaptic layer comprises memory cells of a first type of memory cell and the second type of synaptic layer comprises memory cells of a second type, the first type of memory cell being different than the second type of memory cell. The first and second types of memory cells can be different types of memories, have different structures, different memory materials, and/or different read/write algorithms, any one of which can result in variations in the stability or accuracy of the data stored in the memory cells.
