Abstract: Some embodiments include memory cells having four transistors supported by a base, and vertically offset from the base. The four transistors are incorporated into first and second inverters having first and second inverter outputs, respectively. A first access transistor gatedly couples the first inverter output to a first comparative bitline, and second access transistor gatedly couples the second inverter output to a second comparative bitline. The first and second access transistors have first and second gates coupled to one another through a wordline. The four transistors are along a first side of the wordline, and are vertically displaced from the wordline. The first and second comparative bitlines are laterally adjacent to one another along a second side of the wordline, and are vertically displaced from the wordline. Some embodiments include memory arrays.

Abstract: The present disclosure includes apparatuses and methods related to accessing status information. One example apparatus comprises a host and a memory device coupled to the host. The memory device includes a controller configured to provide, to a status arbiter, a status signal indicating whether a status register of the controller contains generated status information. Responsive to the status signal indicating that the status register contains the generated status information, the controller can also provide the status information from the controller to the status arbiter via a status intermediary.

Abstract: An apparatus can include an array of memory cells coupled to sensing circuitry. The sensing circuitry can include a sense amplifier and a compute component.
