    摘要: A content-addressable memory (CAM) storage element includes bit storage cell bit comparison cells. The bit storage cell is arranged on a first die tier and includes at least one transistor, one or two bit lines, and a storage node. The bit comparison cell is arranged on a second die tier and has a match line, complementary search lines, and at least three transistors. The complementary search lines are decoupled from the bit line(s). A 3D connection couples the storage node to one of the transistors of the second die tier. The CAM cell performs at least one CAM search per clock cycle using at least four transistors per search, including the at least one transistor of the bit storage cell and the at least three transistors of the bit comparison cell, and to output results of the at least one CAM search on the match line.

    摘要: According to one embodiment, a driver that sequentially supplies a first voltage, a second voltage higher than the first voltage, and the first voltage to the bit line, during the writing operation to the first memory cell. The driver supplies a third voltage to the second word line and a fourth voltage to the second selecting gate line while changing the voltage of the bit line from the second voltage to the first voltage if a data is a first data. The driver supplies a fifth voltage to the second word line and a sixth voltage to the second selecting gate line while changing the voltage of the bit line from the second voltage to the first voltage if the data is a second data. At least the sixth voltage is larger than the fourth voltage or the fifth voltage is larger than the third voltage.

    摘要: Methods of operating a number of memory devices are disclosed. A method may include adjusting a count of a refresh address counter of at least one memory device of a number of memory devices such that the count of the refresh address counter of the at least one memory device is offset from a count of a refresh address counter of at least one other memory device of the number of memory devices. The method may also include receiving, at each of the number of memory devices, a refresh command. Further, the method may include refreshing, at each of the number of memory devices, a row of memory cells indicated by the count of an associated refresh address counter. Related systems and memory modules are also described.

    摘要: A semiconductor memory device includes a memory cell; and a page buffer including a sensing circuit that is coupled to the memory cell through a bit line. The page buffer includes a first transistor included in the sensing circuit; and a second transistor not included in the sensing circuit. A cross-sectional dimension of a first contact which is coupled to the first transistor and a cross-sectional dimension of a second contact which is coupled to the second transistor are different from each other. The cross-sectional dimension of the second contact is smaller than the cross-sectional dimension of the first contact.

    摘要: A semiconductor device includes a row address generation circuit, a first region, and a second region. The row address generation circuit is configured to generate a first row address from an active signal and a first bank address and configured to generate a second row address from the active signal and a second bank address. The first region is activated by the first row address and an internal address. The second region is activated by the second row address and the internal address. One of the first and second bank addresses is selectively generated according to a command/address signal.

    摘要: A memory interface circuit, a memory storage device and a signal generation method are provided. The memory interface circuit is configured to connect a volatile memory module and a memory controller. The memory interface circuit includes a clock generation circuit, a first interface circuit and a second interface circuit. The clock generation circuit is configured to provide a reference clock signal. The first interface circuit is configured to provide an address signal to the volatile memory module based on a first transition point of the reference clock signal. The second interface circuit is configured to provide a command signal to the volatile memory module based on a second transition point of the reference clock signal. The first transition point is one of a rising edge and a falling edge of the reference clock signal. The second transition point is the other one of the rising edge and the falling edge of the reference clock signal.

    摘要: According to an exemplary embodiment, a memory device may include a memory cell array that includes memory cells connected to word lines arranged in sequential order depending on a sequential change of a row address, a row decoder that, for each row address input to the row decoder, scrambles a first bit of the row address and a second bit of the row address depending on a selection signal, thereby forming a scrambled row address, decodes the scrambled row address, and selects a word line from the word lines based on the scrambled row address, and an anti-fuse array that includes an anti-fuse in which a logical value of the selection signal is programmed. A first word line and a second word line of the word lines may be adjacent to each other, and a difference between a first value of the row address corresponding to the first word line and a second value of the row address corresponding to the second word line may be a value corresponding to the first bit.
