    摘要: A needle alignment verification circuit includes a sensor pad, a first transmission line, a control element, a data pad, a second transmission line, and a response element. The sensor pad includes an insulation part and a conduction part. The first transmission line is electrically connected to the conduction part and to the interior of the semiconductor device. The control element asserts the first transmission line at a first logic state, and upon receiving the probe signal at the conduction part, transitions the logic state of the first transmission line to a second logic state. The second transmission line provides a predetermined signal to the data pad. The response element controls the second transmission line so that the second transmission line has the state of a verification result voltage for a misalignment state in response to the second logic state.

    摘要: Systems and methods for performing a PASR (partial array self-refresh) operation wherein a refresh operation for recharging stored data is performed on a portion (e.g., ½ ¼, ⅛, or {fraction (1/16)}) of one or more selected memory banks comprising a cell array in a semiconductor memory device. In one aspect, a PASR operation is performed by (1) controlling the generation of row addresses by a row address counter during a self-refresh operation and (2) controlling a self-refresh cycle generating circuit to adjust the self-refresh cycle output therefrom. The self-refresh cycle is adjusted in a manner that provides a reduction in the current dissipation during the PASR operation. In another aspect, a PASR operation is performed by controlling one or more row addresses corresponding to a partial cell array during a self-refresh operation, whereby a reduction in a self-refresh current dissipation is achieved by blocking the activation of a non-used block of a memory bank.
