    Abstract: A random access memory cell and fabrication method therefor are disclosed. The random access memory cell includes a first and a second pull-down transistor cross-coupled such that a control terminal of the first pull-down transistor is connected to a conduction terminal of the second pull-down transistors, and the control terminal of the second pull-down transistor is connected to the conduction terminal of the first pull-down transistor. A first pass gate transistor is coupled between the conduction terminal of the first transistor and a first bit line of a bit line pair, and a second pass gate transistor is coupled between the conduction terminal of the second transistor and a second bit line of the bit line pair. The threshold voltage of the first and second pass gate transistors is such that a subthreshold current is provided to the first and second pull-down transistors when the memory cell is not being accessed such that the conduction terminal of the pull-down transistor that is turned off is maintained at a voltage level corresponding to a logic high voltage. In this way, the memory cell is capable of performing a latching function without pull-up transistors.

    Abstract: A device for reading/rewriting a memory cell of a dynamic random-access memory organized in rows and columns, comprises, for each column, a first read/rewrite amplifier, and at least one second read/rewrite amplifier arranged in parallel with the first amplifier. A controller is provided for one of the amplifiers so that the amplifier is able to store the information contained in the memory cell for refreshing thereof, and so that the other amplifier is able to simultaneously perform read/rewrite accesses to and from the memory cell. One of the amplifiers may be permanently dedicated to operations for refreshing the memory cells and the other may be dedicated to read/write operations. Outputs of the amplifiers are connected to common output columns, and the controller includes an interrupter for the output of each amplifier to isolate the output from the corresponding output column and from the corresponding output of the other amplifier.

    Abstract: A memory device includes a defect memory, a test circuit, and a spare memory. The defect memory and the spare memory have as many rows as the array, and each row of the defect memory and the spare memory are selected when the corresponding row of the array is selected. A test circuit locates defective cells of the array and writes addresses in the defect memory to indicate locations of the defective cells. Additionally, a control circuit selects a row of the array based on a selected row address and redirects access to the corresponding row of the spare memory whenever a selected column address corresponds to one of the addresses stored in the defect memory. In one preferred embodiment, each of the rows of the defect memory stores information indicating if there is a defective cell in the corresponding row of the array and the column address of the defective cell. A computer system including such a memory device is also provided.
