  • Patent number: 11942137
    Abstract: A memory controller, to control a semiconductor memory device, includes an access pattern profiler, a row hammer prediction neural network, and a memory interface. The access pattern profiler generates an access pattern profile based on a row access pattern on a portion of memory cell rows of the semiconductor memory device during a reference time interval posterior to a refresh interval during which the memory cell rows are refreshed. The row hammer prediction neural network predicts a probability of occurrence based on the access pattern profile. In response to the probability being equal to or greater than a reference value, the row hammer prediction neural network generates a hammer address, an alert signal indicating that the row hammer occurs, and an outcast row list. The memory interface transmits the hammer address, the outcast row list, and the alert signal to the semiconductor memory device.

  • Patent number: 11935607
    Abstract: An integrated circuit die includes memory sectors, each memory sector including a memory array. The die includes a voltage regulator with a first transistor driven by an output voltage to thereby generate a gate voltage, the output voltage being generated based upon a difference between a constant current and a leakage current. A selection circuit selectively couples the gate voltage to a selected one of the plurality of memory sectors. A leakage detector circuit drives a second transistor with the output voltage to thereby generate a copy voltage based upon a difference between a variable current and a replica of the constant current, increases the variable current in response to the copy voltage being greater than the gate voltage, and asserts a leakage detection signal in response to the copy voltage being less than the gate voltage, the leakage detection signal indicating excess leakage within the memory array.

The functional data includes write bits and mask bits associated with the write bits. One or more mask bits having a first logic state indicate that associated one or more write bits are to be written to the register, respectively. Based on the address, the register management system selects a first half of the register or a second half of the register to perform the write operation. Further, the register management system writes the one or more write bits associated with the one or more mask bits having the first logic state to one or more storage elements of the first half of the register or the second half of the register, respectively.

  • Patent number: 11923027
    Abstract: Methods, systems, and devices for read command fault detection in a memory system are described. For example, a memory device may be configured to set a field of a register with a first value, corresponding to a state where a read command has not been decoded. If the memory device receives and decodes a read command from a host device, the memory device may set the field with a second value. The memory device indicate a value of the field of the register to the host device, which may be used to evaluate whether to process information interpreted over an interface between the host device and the memory device. For example, if the host device receives an indication of the second value, the host device may proceed with processing and, if the host device receives an indication of the first value, the host device may refrain from processing.

  • Patent number: 11908525
    Abstract: When selectively erasing one sub-block, a control circuit applies, in a first sub-block, a first voltage to bit lines and a source line, and applies a second voltage smaller than the first voltage to the word lines. Then, the control circuit applies a third voltage lower than the first voltage by a certain value to a drain-side select gate line and a source-side select gate line, thereby performing the erase operation in the first sub-block. The control circuit applies, in a second sub-block existing in an identical memory block to the selected sub-block, a fourth voltage substantially identical to the first voltage to the drain side select gate line and the source side select gate line, thereby not performing the erase operation in the second sub-block.
