摘要:
A data output circuit for an integrated circuit memory device includes a control circuit that is configured to generate a plurality of clock signals responsive to at least a portion of a memory column address, and a multiplexer circuit that is configured to output memory data received on input terminals thereof onto an output terminal responsive to selective invocation of the plurality of clock signals. The clock signals are invoked in an order based on the at least a portion of the memory column address.
摘要:
A full-stress testable memory device having an open bit line architecture and a method of testing the memory device. The memory device of the invention includes dummy bit lines, and a voltage controller connected to the dummy bit lines. The voltage controller alternately provides a first variable control voltage and a second variable control voltage to the dummy bit lines during a test mode. In accordance with a method of testing the memory device, a fixed voltage is provided to the dummy bit lines of the edge sub-arrays during a normal operation mode. However, during a test mode, the fixed voltage being applied to the dummy bit line is replaced with a supply voltage and/or a ground voltage, so that all of the sub-arrays can be equally tested.

An integrated circuit memory device includes a memory cell array, a plurality of data input lines configured to convey data to the memory cell array and a plurality of data output lines configured to convey data from the memory cell array. The device also includes a memory write buffer that receives write data for the memory cell array and responsively drives the data input lines, a sense amplifier and a plurality of sense amplifier input lines configured to convey data to the sense amplifier. The device further includes a selecting circuit coupled to the data input lines, to the data output lines and to the sense amplifier input lines and configured to selectively couple the data input lines to the sense amplifier input lines responsive to a control signal.
