    Abstract: Apparatuses and methods for triggering row hammer address sampling are described. An example apparatus includes an oscillator circuit configured to provide a clock signal, and a filter circuit. The filter circuit includes a control circuit configured to receive pulses of the clock signal and provide an output signal that represents a count number by counting a number of pulses of the clock signal and control a probability of enabling the output signal based on the count number. The filter circuit further includes a logic gate configured to pass one of the pulses of the clock signal responsive to the output signal from the control circuit being enabled and filter another of the pulses responsive to the output signal from the control circuit being not enabled.

An example apparatus may include an address scrambler and a refresh control circuit. The address scrambler may receive a first address, output a second address in response to a first control signal, and output a third address in response to a second control signal. The second address may physically adjacent to the first address and the third address may physically adjacent to the second address. The refresh control circuit may perform a refresh operation on the second address when the first control signal is active and perform the refresh operation on the third address when the second control signal is active.

    Abstract: 【課題】内部クロック信号の生成によって生じる消費電流を削減する。 【解決手段】チップセレクト信号CS_nの活性化に応答して内部クロック信号PCLKARの生成を開始するクロック信号バッファ回路90と、内部クロック信号PCLKARに同期して動作する内部回路70,100,110,120を備える。クロック信号バッファ回路90は、コマンド信号CA0~CA9がリードコマンドを示している場合には第2のタイミングで内部クロック信号PCLKARの生成を停止し、コマンド信号CA0~CA9がアクティブコマンドを示している場合には第2のタイミングよりも早い第1のタイミングで内部クロック信号PCLKARの生成を停止する。本発明によれば、外部コマンド信号に応じて必要な期間だけ内部クロック信号が生成されることから、消費電流を削減することが可能となる。

In one particular exemplary embodiment, the techniques may be realized as a method for reducing impact of array disturbs in a semiconductor memory device by increasing the refresh rate to the semiconductor memory device based at least in part on a frequency of active operations. The method may comprise receiving a first refresh command including a first subarray address to perform a first refresh operation to a first logical subarray of memory cells associated with the first subarray address. The method may also comprise receiving a second refresh command including a second subarray address to perform a second refresh operation to a second logical subarray of memory cells associated with the second subarray address, wherein the second refresh command is received after a time period from the reception of the first refresh command. The method may further comprise performing a number of concurrent refresh operations during the time period.
