Abstract: In a drive unit for a luminescence display panel employing organic EL elements as light-emitting elements and capable of reducing power consumed by the display panel when a partial scan mode is selected, when the partial scan mode is selected by a scan mode switching mean, a control is performed so that the ratio of a drive period (D3), during which the light emission of the light-emitting elements is controlled, to a reset period (R1) set by a reset control means is increased as compared with a case in which the ordinary scan mode is selected. Thus, the momentary luminance of the light-emitting elements can be lowered by further reducing drive currents or drive voltages supplied to the respective light-emitting elements. Accordingly, it is possible to further reduce the power consumption of the luminescence display panel as well as to prevent the deterioration of the light-emitting elements, which contributes to extend the life of the light-emitting elements.

Abstract: A memory device includes multiple data I/O lanes and corresponding lane or column decoders. Instead of providing the same address to each column decoder, decoder logic calculates potentially different column addresses depending on the needs of the device utilizing the memory. For example, the column addresses might be based on a received CAS address and an accompanying offset. This allows data access at alignments that do not necessarily correspond to CAS alignments. . The technique is utilized in conjunction with graphics systems in which tiling is used. In systems such as this, memory offsets are specified in terms of pixel columns and rows. The technique is also used in conjunction with a router such as a TCP/IP router, in which individual packets are aligned at CAS boundaries. In this situation, the decoder logic is alternatively configurable to allow access of either an information packet or a plurality of packet headers during a single memory access cycle.
