  • Publication number: 20240071431
    Abstract: Systems and method for sensing an accessed voltage value associated with a memory cell is described. In different embodiments, a memory array may include a different number of sense components. Moreover, each sense component may receive latching signals to latch the accessed voltage value of memory cells of the memory array based on different timings. For example, the memory array may latch digit line voltages of memory cells positioned farther from a respective word line driver at a later time based on a latching signal with a higher delay. Such memory arrays may include circuitry to receive and/or generate the delayed latching signals as well as selection circuitry for latching the digit line voltages based on a selected delayed latching signals.

  • Publication number: 20240071456
    Abstract: Systems and method for sensing an accessed voltage value associated with a memory cell is described. In different embodiments, a memory array may include a different number of sense amplifiers. Moreover, each sense amplifier may include capacitors with different capacitance values to compensate for a difference in received charges associated with a similar memory state caused by various circuit delays. For example, farther memory cells from a word line driver may receive activation signals with higher delays which in turn may result in delayed activation. As such, the sense amplifiers may include capacitors with varying capacitance values to compensate for an amount charge received at a latching time caused by delayed provision of charges associated with the targeted memory states.

  • Publication number: 20240004751
    Abstract: An on-die controller can provide an error correction capability for data stored in an array of memory cells located on the same die as the on-die controller. The error correction capability provided by the on-die controller eliminates a need to transfer error correction code (ECC) data to an external controller that may have provided the error correction capability in lieu of the on-die controller, which can provide more channel bandwidth for other types of non-user data for further strengthening data reliability, security, integrity of the memory system.

  • Patent number: 11804281
    Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for automatic soft post-package repair (ASPPR). A memory may receive a row address along with a signal indicating an ASPPR operation, such as a bad page flag being set. A word line engine generates a physical address based on the row address, and ASPPR registers stores the physical address. The time it takes from receiving the row address to storing the physical address may be within the timing of an access operation on the memory such as tRAS. The row address may specify a single page of information. If the bad page flag is set, then a subsequent PPR operation may blow fuses to encode the physical address stored in the ASPPR registers.

  • Patent number: 11594272
    Abstract: Devices and methods for sensing a memory cell are described. The memory cell may include a ferroelectric memory cell. During a read operation, a first switching component may selectively couple a sense component with the memory cell based on a logic state stored on the memory cell to transfer a charge between the memory cell and the sense component. A second switching component, which may be coupled with the first switching component, may down convert a voltage associated with the charge to another voltage that is within an operation voltage of the sense component. The sense component may operate at a lower voltage than a voltage at which the memory cell operates to reduce power consumption in some cases.

  • Patent number: 11282560
    Abstract: Methods, systems, and devices for temperature-based access timing for a memory device are described. In some memory devices, accessing memory cells may be associated with different operations that are variously dependent on a temperature of the memory device. For example, some operations associated with accessing a memory cell may have a longer duration and others a shorter duration depending on the temperature of the memory device. In accordance with examples as disclosed herein, a memory device may be configured for performing some portions of an access operation according to a duration that is proportional to a temperature of the memory device, and performing other portions of the access operation according to a duration that is inversely proportional to a temperature of the memory device.

  • Patent number: 11262941
    Abstract: Apparatuses and methods including memory commands for semiconductor memories are described. An example method includes receiving a data clock signal responsive to receiving a timing command, performing an access operation responsive to receiving an access command associated with the timing command, providing an access data clock signal based on the data clock signal, and providing an access data clock signal based on the data clock signal. The access command may be separated in time from the associated timing command by at least one clock cycle of a system clock signal. In some examples, the access command may precede the associated timing command or may follow the associated timing command. In some examples, the access command may immediately follow or precede the associated timing command.
