    Abstract: A sense amplifier for use in a serial configuration memory includes multiple stages which are enabled and disabled in a controller manner, in response to a control pulse. The control pulse is produced every Nth period of an externally provided clock signal, the clock being used to clock out a bitstream representing the contents of the memory device. In a preferred embodiment, N such sense amps are utilized to read out in parallel fashion the N memory cells (bits) that constitute an accessed memory location. The sense amps are therefore active only of a period of time sufficient to read out a memory cell.

    Abstract: A memory circuit (14) having features specifically adapted to permit the memory circuit (14) to serve as a video frame memory is disclosed. The memory circuit (14) contains a dynamic random access memory array (24) with buffers (18, 20) on input and ouput data ports (22) thereof to permit asynchronious read, write and refresh accesses to the memory array (24). The memory circuit (14) is accessed both serially and randomly. An address generator (28) contains an address buffer register (36) which stores a random access address and an address sequencer (40) which provides a stream of addresses to the memory array (24). An initial address for the stream of addresses is the random access address stored in the address buffer register (36).

    Abstract: A semiconductor memory is disclosed which comprises a memory array, an address counter designating the address of the memory array, a shift register to which the data signals read out from the memory array are preset, and a control circuit. When all the data preset to the shift register is shifted out to an external terminal, the control circuit updates the address counter. The data produced from the new address of the memory array is again preset to the shift register. The same operation is thereafter repeated, thereby producing serial data signals at the external terminal. The semiconductor memory having such a construction can read out continuous data signals without any need for external address signals.

    Abstract: A row hammer control method and a memory device are provided. The memory device monitors the row hammer address(es) having the number of accesses equal to or more than a predetermined number of times or having a higher number of accesses as compared with other access addresses during the first row hammer monitoring time frame and malicious row hammer address(es) accessed at random sampling time points during the second row hammer monitoring time frame and being the same as the row hammer address(es), notifies a memory controller of the malicious row hammer address(es) when the number of malicious row hammer addresses exceeds a threshold value, and causes a target refresh a memory cell row physically adjacent to a memory cell row corresponding to the malicious row hammer address(es) to be performed.

    Abstract: Disclosed herein are related to operating a memory system including memory banks and buffers. Each buffer may perform a write process to write data to a corresponding memory bank. In one aspect, the memory system includes a buffer controller including a queue register, a first pointer register, a second pointer register, and a queue controller. In one aspect, the queue register includes entries, where each entry may store an address of a corresponding memory bank. The first pointer register may indicate a first entry storing an address of a memory bank, on which the write process is predicted to be completed next. The second pointer register may indicate a second entry to be updated. The queue controller may configure the queue register according to the first pointer register and the second pointer register, and configure one or more buffers to perform the write process, according to the entries.
