    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.

    摘要: A system is capable of receiving Fast Page mode, Extended Data Out mode, Burst Extended Data Out mode, or a combination of these memory devices. A method of determining the type of memory present allows the system to adjust internal memory access signals in accordance with the type of memory installed. The system may be shipped with a first type of memory, and then upgraded to a second type of memory by the user to improve overall system performance. A first bank of memory may be of a first type, and a second bank may be of another type. The user may make cost versus performance decisions when upgrading memory types or capacities.
