摘要: A DDR DRAM having a test mode and an operational mode and a method for testing the DDR DRAM. The method includes in the order recited: (a) placing the DDR DRAM in test mode; (b) issuing a band activate command to select and bring up a wordline selected for write of the DDR DRAM; (c) writing with auto-precharge, a test pattern to cells of the DDR DRAM; (d) repeating steps (b) and (c) until all wordlines for write have been selected; (e) issuing a bank activate command to select and bring up a wordline selected for read of the DDR DRAM; (f) reading with auto-precharge, the stored test pattern from cells of the DDR DRAM; and (g) repeating steps (c) and (f) until all wordlines for read have been selected.

摘要: A welding method and machine for fabricating a wire network by supporting a group of wires in spaced side by side relation, intermittently advancing the wire group endwise through a welding station, and following each advance of the wire group, supporting at least one wire within the welding station in a transverse welding position relative to the group wires, such that the group and transverse wires cross one another, and welding the group and transverse wires to one another at their crossing points to form a welded wire network comprising the group wires and a multiplicity of transverse wires spaced along and welded to the group wires. The invention is described in connection with fabricating gore shaped wire networks which may be assembled to form a parabolic antenna reflector.
