Patent number: 6584543Abstract: A memory structure includes a memory module divided into low order banks and high order banks. The low order banks are used as conventional memory. The high order banks are used as either conventional memory or ECC memory, depending upon routing of data. In one embodiment, data from the high order banks are routed through a primary multiplexer to a data bus when the high order banks are used as conventional memory. When the high order banks are used as ECC memory, data from the auxiliary section is routed through the primary multiplexer to an error correction circuit. A secondary multiplexer combines ECC bits from the auxiliary section of the module or a dedicated ECC memory on a motherboard. The auxiliary section thus supplements the onboard ECC memory to provide support for an effectively larger ECC memory for use with error intolerant applications that require error correction.Type: GrantFiled: November 14, 2002Date of Patent: June 24, 2003Assignee: Micron Technology, Inc.Inventors: Brett L. Williams, Donald D. Baldwin

Patent number: 6094702Abstract: An application-specific integrated circuit (ASIC) for enabling access to memory. ASIC includes a decryptor, a valid authorization storage component, an upgrade verifier, an upgrade storage component, and an enabling component. The decryptor inputs an encrypted authorization code and outputs a decrypted authorization code. The valid authorization storage component stores and outputs a valid authorization code. The upgrade verifier inputs the decrypted authorization code and the valid authorization code, compares the decrypted authorization code to the valid authorization code to determine whether access to the portion of memory is authorized, and outputs a signal to enable access to the portion of memory. The upgrade storage component stores the signal output from the upgrade verifier. The enabling component inputs a memory access signal and a signal stored in the upgrade storage component and outputs a signal indicating whether the portion of memory is enabled.Type: GrantFiled: October 30, 1997Date of Patent: July 25, 2000Assignee: Micron Technology, Inc.Inventors: Brett L.
