In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "In accordance with the present disclosure, a dynamic random access memory (DRAM) component is described. The DRAM component may comprise an integrated circuit, with the integrated circuit including an array of volatile memory cells. A first volatile memory cells of the array of volatile memory cells may be defective. The integrated circuit may also include non-volatile memory, and the non-volatile memory may contain a reference to the first volatile memory cell.
"The system and method disclosed herein is technically advantageous because it allows references to defective volatile memory cells within DRAM memory to be stored on die. Specifically, references to defective volatile memory cells may be identified and stored while the DRAM memory is still being manufactured. The references may be retrieved later and the defective volatile memory cells may be mapped out of usable memory space. This may reduce or eliminate the need for redundant cells within the DRAM memory, which may decrease the cost, and increase the amount of space within DRAM memory for additional storage cells. Other technical advantages will be apparent to those of ordinary skill in the art in view of the following specification, claims, and drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
"A more complete understanding of the present embodiments and advantages thereof may be acquired by referring to the following description taken in conjunction with the accompanying drawings, in which like reference numbers indicate like features, and wherein:
"FIG. 1 shows an example information handling system.
"FIG. 2 shows an example memory module incorporating a DRAM component, according to aspects of the present disclosure.
"FIG. 3 shows an example DRAM component, according to aspects of the present invention.
"FIG. 4 shows an example method incorporating aspects of the present disclosure.
"FIG. 5 shows an array of volatile memory cells and a memory defect map, according to aspects of the present disclosure.
"While embodiments of this disclosure have been depicted and described and are defined by reference to exemplary embodiments of the disclosure, such references do not imply a limitation on the disclosure, and no such limitation is to be inferred. The subject matter disclosed is capable of considerable modification, alteration, and equivalents in form and function, as will occur to those skilled in the pertinent art and having the benefit of this disclosure. The depicted and described embodiments of this disclosure are examples only, and not exhaustive of the scope of the disclosure."
