    摘要: A memory system includes a memory array, a plurality of wordline drivers, a row address decoder block which has a plurality of outputs connected to selected ones of the wordline drivers, a row selector block which has a selector lines connected to individual ones of the wordline drivers. A power management circuit having a power down input for a power down input signal (WLPWRDN) and a wordline power down output (WLPDN) is connected to the wordline drivers to lower the power consumption thereof as a function of the power down input signal.

    摘要: A method for planarizing a layer of photoresist on a substrate. The layer of photoresist is exposed to wavelengths of radiation that the photoresist is sensitive to. The radiation is directed at the layer of photoresist at an oblique angle with respect to a major dimension of the layer of photoresist. The photoresist is developed.

    摘要: In a DRAM, which includes a plurality of memory banks, there is a pair of separate flag bit registers for each bank with the flag bit registers that are shifted up/down respectively. A comparator for each bank provides a comparator output. An arbiter for each bank is connected to receive a flag bit up signal and a flag bit down signal from the flag bit registers for that bank and the comparator output from the comparator for that bank. The arbiters are connected to receive a conflict in signal and to provide a conflict out signal. The pair of flag bit registers represent a refresh status of each bank and designate memory banks or arrays that are ready for a refresh operation.
