    摘要: A computing device in some examples includes an array of memory cells, such as 8-transisor SRAM cells, in which the read bit-lines are isolated from the nodes storing the memory states such that simultaneous read activation of memory cells sharing a respective read bit-line would not upset the memory state of any of the memory cells. The computing device also includes an output interface having capacitors connected to respective read bit-lines and have capacitance that differ, such as by factors of powers of 2, from each other. The output interface is configured to charge or discharge the capacitors from the respective read bit-lines and to permit the capacitors to share charge with each other to generate an analog output signal, in which the signal from each read bit-line is weighted by the capacitance of the capacitor connected to the read bit-line. The computing device can be used to compute, for example, sum of input weighted by multi-bit weights.

    摘要: Methods, systems, and devices for lateral split digit line memory architectures are described. A memory array may include a first set of word line plates separated from a second set of word line plates by a pillar (e.g., that is configured as a digit line) that interact with the first and second set of word line plates. Further, the memory array may include a set of dielectric piers that are positioned between the pillars, where each dielectric pier contacts a first pillar and a second pillar. Additionally, the memory array may include a set of storage elements and a set of digit lines that are each coupled with a word line plate, a pillar, and a dielectric material that is positioned between each first and second pillar of the pairs of pillars.

    摘要: Pre-charge voltage generation circuit for a random memory and a random memory are provided. The pre-charge voltage generation circuit is configured to selectively provide a pre-charge voltage and includes: a voltage generation module, configured to generate a first voltage and a second voltage, wherein either of the first voltage and the second voltage serves as the pre-charge voltage, the first voltage is greater than the second voltage; a selection module, coupled to the voltage generation module, configured to select and output the second voltage as the common end voltage of the storage capacitor of the random memory in response to an operation command being a write command, and configured to select and output the first voltage as the common end voltage in response to the operation command being a read command.
