Abstract:
A refreshable dynamic memory system having a memory array, comprising:an enabling device enabling use of said refreshable dynamic memory system with said memory array, said device including a plurality of programmable elements selected from the group comprising a fuse and an anti-fuse;said memory array comprising:a plurality of pairs of complementary digit lines;a plurality of word lines;a plurality of memory cells each having a control terminal coupled to one of the word lines and an access terminal coupled to one of the digit lines, at least two memory cells of the plurality of memory cells connected to each digit line of a pair of the plurality of pairs of complementary digit lines, each memory cell having a row address;refresh counter and address buffer circuitry for generating row addresses;row decoder circuitry coupled to the word lines and the address buffer circuitry for energizing at least two word lines in the array in accordance with each generated row address;sense amplifier circuitry coupled to the digit lines for accessing and refreshing the memory cells coupled to each of the energized word lines; andenergizing circuitry coupled to the enabling device for energizing more than one of the word lines of the plurality of word lines in the memory array in accordance with each row address for a memory cell of the plurality of memory cells in response to the enabling device enabling use of the refreshable dynamic memory system having the memory array so more than one memory cell of the plurality of memory cells accessible through the pair of complementary digit lines may be accessed for each row address.
