  • Dynamic random access memory system with a static random access memory interface and methods for using the same
    Patent number: 6233193
    Abstract: A memory 700 having an array 701 of rows and columns of dynamic memory cells 301, cells 301 of each row coupled to a refresh wordline 303a and an access wordline 303b and cells 301 of each column coupled to a refresh bitline 302a and an access bitline 302b. Refresh circuitry 711, 712, refreshes selected rows of cells corresponding to a refresh wordline 303a and a corresponding one refresh bitline 302a. Access circuitry accesses selected cells of a selected row using corresponding access wordline 303b and corresponding one of the access bitlines 302b. The access circuitry includes a new address detector of 709 for detecting receipt of a new address of said memory, a row decoder 702 for selecting access wordline in response to receipt of the new address and access sense amplifiers 703 and an access column decoder 704 accesses at least one cell along the selected wordline 303b using the corresponding access bitline 302b.
