Abstract: An in-memory computing memory device is disclosed. The memory device comprises an array of memory cells, a plurality of word lines, a plurality of bit lines, (M+1) input circuits, a wordline driver and an evaluation circuitry. The array is divided into (M+1) lanes and each lane comprises P memory cell columns and an input circuit. The input circuit in each lane charges a predefined bit line with a default amount of charge proportional to an input synapse value and then distributes the default amount of charge to the other second bit lines with a predefined ratio based on a constant current. The evaluation circuitry couples a selected number of the bit lines to an accumulate line and convert an average voltage at the accumulate line into a digital value in response to a set of (M+1) input synapse values and the activated word line.

Abstract: An integrated circuit applied in a deep neural network is disclosed. The integrated circuit comprises at least one processor, a first internal memory, a second internal memory, at least one MAC circuit, a compressor and a decompressor. The processor performs a cuboid convolution over decompression data for each cuboid of an input image fed to any one of multiple convolution layers. The MAC circuit performs multiplication and accumulation operations associated with the cuboid convolution to output a convoluted cuboid. The compressor compresses the convoluted cuboid into one compressed segment and store it in the second internal memory. The decompressor decompresses data from the second internal memory segment by segment to store the decompression data in the first internal memory. The input image is horizontally divided into multiple cuboids with an overlap of at least one row for each channel between any two adjacent cuboids.

Abstract: The invention provides a method for performing copy back operations. First, a copy back command is sent to a flash memory for reading a first error correction code (ECC) data from a first address. The first ECC data is then received from the flash memory. The first ECC data is then decoded without performing error correction to calculate a fail count of the first ECC data. The fail count is then compared with a first threshold value. When the fail count is less than the first threshold value, a first program command is sent to the flash memory for storing the first ECC data to a second address of the flash memory. When the fail count is less than the first threshold value, the first ECC data is not sent back to the flash memory.

Abstract: A flash memory device includes a memory array and a memory control circuit. The memory array includes memory modules. Each memory module is located in a memory channel and includes a predetermined number of memory cells. The memory control circuit is coupled to the memory array via an address latch enable (ALE) pin and a command latch enable (CLE) pin. The ALE pin and the CLE pin are coupled to all of the memory cells and shared by all of the memory cells in the memory array.

Abstract: The present invention discloses an XOR-based conditional keeper and an architecture implementing its application to match lines, wherein the XOR gate in the conditional keeper receives a clock signal synchronous with CAM (Content Addressable Memory) cells and cooperates with a floating signal from the floating node to create an XOR control signal, and the XOR control signal is transmitted to a P-type transistor to create a data signal to control the XOR-based conditional keeper so that the XOR-based conditional keeper can execute an appropriate corresponding action, which can replace the conventional keepers of merely “on” and “off” modes. Further, the XOR-based conditional keeper of the present invention can apply to the dynamic CAM match line architecture so that the dynamic match line can have lower power consumption, higher noise immunity, and high processing speed.
