    Abstract: Aspects of the present disclosure eliminating the need for a memory device to have both a shifter that shifts input pin values from an input domain into a parity domain and another shifter that shifts a decoded command from the input domain into the parity domain. A memory device can achieve this by, when parity is being performed, shifting the input from the input pins into the parity domain prior to decoding the command. Using a multiplexer, the decoder can receive the command pin portion of the shifted input when parity checking is being performed and can receive the un-shifted command pin input when parity checking is not being performed. The decoder can use the command pin portion of the shifted input to generate shifted and decoded commands or can use the un-shifted command pin input to generate decoded commands.

  • Patent number: 10566040
    Abstract: Methods, systems, and devices for operating a memory array with variable page sizes are described. The page size may be dynamically changed, and multiple rows of the memory array may be accessed in parallel to create the desired page size. A memory bank of the array may contain multiple memory sections, and each memory section may have its own set of sense components (e.g., sense amplifiers) to read or program the memory cells. Multiple memory sections may thus be accessed in parallel to create a memory page from multiple rows of memory cells. The addressing scheme may be modified based on the page size. The logic row address may identify the memory sections to be accessed in parallel. The memory sections may also be linked and accessing a row in one section may automatically access a row in a second memory section.

  • Patent number: 10530616
    Abstract: A transmitting device includes an output node, at least one driver circuit and transition equalization circuitry. The driver circuit drives an output data signal including a data transition onto the output node. The output of the transition equalization circuitry is coupled to the output node. The transition equalization circuitry begins to drive the output node at the data transition and ends driving of the output node a pre-determined delay after beginning to drive the output node. The transition equalization circuitry drives the output node by injecting current onto the output node if the data transition is a positive transition, and sinking current from the output node if the data transition is a negative transition.
