Abstract: A method and apparatus for programming a data strobe (DQS) preamble in a memory by loading a defined set of bits into one or more registers of the memory, where one or more bits are formatted specifically for enabling the data strobe preamble. At least one of the bits is used to enable a data strobe preamble as either a default data strobe preamble of the memory or as a reduced data strobe preamble with a time length set equal to a fraction of the default preamble or a fraction of a clock cycle. The enabling bit can be used to provide a input for generating a delay that provides a delayed signal to drivers of the memory for producing a reduced data strobe preamble and for sequencing or driving data to be read out of the memory. The reduced data strobe preamble can also be used for writing data into the memory.

Abstract: Methods of configuring a system. More specifically, operating current values corresponding to respective memory devices of memory module may be stored in programmable elements, such as antifuses, located on the memory device, during fabrication. The operating current values may be read from and/or stored in a non-volatile memory device on the memory module. Once the memory module is incorporated into a system, the programmable elements on the memory devices and/or the non-volatile memory device on the memory module may be accessed such that the system can be configured to optimally operate in accordance with the operating current values measured for each memory device in the system.

Abstract: Memory modules and methods for fabricating and implementing memory modules wherein unique operating current values corresponding to specific memory devices on the memory modules are accessed from a database such that the operating current values may be implemented to improve system performance. Memory modules comprising a number of volatile memory devices may be fabricated. Operating current values corresponding to the specific memory devices on the memory module may be stored in a database and accessed during fabrication or during implementation of the memory modules in a system. System performance may be optimized by implementing the unique operating current values corresponding to the specific memory devices on the memory modules.
