摘要: A charge sharing scheme is used to mitigate the variations in cell currents in order to achieve higher accuracy for CIM computing. In some embodiments, a capacitor is associated with each SRAM cell, and the capacitors associated with all SRAM cells in a column are included in averaging the RBL current. In some embodiments, a memory unit associated to an RBL in a CIM device includes a storage element adapted to store a weight, a first switch device connected to the storage element and adapted to be controlled by an input signal and generate a product signal having a magnitude indicative of the product of the input signal and the stored weight. The memory unit further includes a capacitor adapted to receive the product signal and store an amount of charge corresponding to the magnitude of the product signal. The memory unit further include a second switch device adapted to transfer the charge on the capacitor to the RBL.

摘要: Disclosed herein are related to a memory system including unit storage circuits. In one aspect, each of the unit storage circuits abuts an adjacent one of the unit storage circuits. In one aspect, each of the unit storage circuits includes a first group of memory cells, a second group of memory cells, a first sub-word line driver to apply a first control signal to the first group of memory cells through a first sub-word line extending along a direction, and a second sub-word line driver to apply a second control signal to the second group of memory cells through a second sub-word line extending along the direction. In one aspect, the memory system includes a common word line driver abutting one of the unit storage circuits and configured to apply a common control signal to the unit storage circuits through a word line extending along the direction.

摘要: A memory macro includes a first memory cell array, a first tracking circuit, a first and a second transistor. The first memory cell array includes rows of memory cells and columns of memory cells. The first tracking circuit includes a first set of memory cells configured as a first set of loading cells responsive to a first control signal, a second set of memory cells configured as a first set of pull-down cells responsive to a second control signal, and a first tracking bit line coupled to the first and second set of memory cells. The first set of pull-down cells or loading cells is configured to track a memory cell of the first memory cell array. The first and second transistor are coupled to the first tracking bit line, and configured to charge the first tracking bit line to a pre-charge voltage level responsive to a tracking enable signal.

摘要: Circuit devices, such as integrated circuit devices, are constructed with combination circuits that include two or more cascading transistors, and one or more metal layers disposed over the cascading transistors. The cascading transistors include multiple internal nodes (e.g., common source/drain regions). The multiple internal nodes are not connected to a common metal stripe (the same metal stripe) in the one or more metal layers. The absence of the connections between the internal nodes and a common metal stripe reduce or eliminate the load on the internal nodes. The transistors in the cascading transistors are independent of each other.

摘要: A memory circuit includes a NAND logic gate, a first N-type transistor, a second N-type transistor, a first inverter and a first latch. The NAND logic gate is configured to receive a first bit line signal and a second bit line signal, and to generate a first signal. The first N-type transistor is coupled to the NAND logic gate, and configured to receive a first pre-charge signal. The second N-type transistor is coupled to the first N-type transistor and a reference voltage supply, and configured to receive a first clock signal. The first inverter is coupled to the NAND logic gate, and configured to output a data signal inverted from the first signal. The first latch is coupled to the NAND logic gate, and configured to latch the first signal in response to at least the first clock signal or the first pre-charge signal.
