    摘要: 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.

    摘要: 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.

    摘要: An integrated circuit memory device is designed for high speed data access and for compatibility with existing memory systems. An address strobe signal is used to latch a first address. During a burst access cycle the address is incremented internal to the device with additional address strobe transitions. A new memory address is only required at the beginning of each burst access. Read/Write commands are issued once per burst access eliminating the need to toggle the Read/Write control line at the device cycle frequency. Transitions of the Read/Write control line during a burst access will terminate the burst access, reset the burst length counter and initialize the device for another burst access. The device is compatible with existing Extended Data Out DRAM device pinouts, Fast Page Mode and Extended Data Out Single In-Line Memory Module pinouts, and other memory circuit designs. Additionally, a DRAM is provided having both pipelined and burst Extended Data Out modes of operation and the ability to switch between them.

    摘要: A counter comprised of two flip flops and a multiplexer produces a sequential or interleaved address sequence. The addresses produced are used to access memory elements in a Burst Extended Data Output Dynamic Random Access Memory (Burst EDO or BEDO DRAM). Input addresses in combination with a sequence select signal are logically combined to produce a multiplexer select input which selects between true and compliment outputs of a first flip flop to couple to an input of a second flip flop to specify a toggle condition for the second flip flop. Outputs of the counter are compared with outputs of an input address latch to detect the end of a burst sequence and initialize the device for another burst access. A transition of the Read/Write control line during a burst access will terminate the burst access and initialize the device for another burst access.
