Patent number: 6324109Abstract: When starting a power, the precharge potential is supplied to all the bit lines and virtual GND lines by VREF potential supply circuits. In a read operation, after the end of a period during which the bit lines of the selected memory block are sensed by memory cells, the precharge potential is immediately supplied to the bit lines and the virtual GND lines, which have been selected, by the VREF potential supply circuits. By this operation, the precharge potential of all the bit lines and the virtual GND lines is maintained prior to the read operation. With this arrangement, a semiconductor storage device capable of increasing the access time speed without bit line division is provided.Type: GrantFiled: June 29, 2000Date of Patent: November 27, 2001Assignee: Sharp Kabushiki KaishaInventor: Kouji Inoue

Patent number: 6240049Abstract: In a synchronous semiconductor storage device, upon latching potentials of a bit line by a sense amplifier in a read operation, a bit line disconnecting circuit disconnects the bit line and an associated reference line from the sense amplifier until a next read operation. At the same time, a virtual GND line disconnecting circuit disconnects a corresponding virtual GND line from the ground potential until the next read operation. After the disconnection of the bit line, the reference line, and the virtual line, the precharge operation of the bit line and virtual line by the VREF level supply circuits is performed in parallel with the amplifying operation by the sense amplifier. This allows an access with a CAS latency of 3.Type: GrantFiled: June 29, 2000Date of Patent: May 29, 2001Assignee: Sharp Kabushiki KaishaInventor: Kouji Inoue

Patent number: 5313428Abstract: A field memory self-refreshing device self-refreshes a field memory with a refresh clock signal derived from a reference clock and a self-refresh clock signal not derived from the reference clock. The field memory self-refreshing device has a reference clock stop determination circuit, a self-refresh clock generator and a refresh clock switching circuit. The reference clock stop determination circuit detects that input from the reference clock has stopped and outputs a reference clock stop signal when input from the reference clock stops. The self-refresh clock generator generates the basis for the self-refresh clock signal used for self-refreshing of the field memory when the reference clock stops. When the refresh clock switching circuit receives the reference clock stop signal from the reference clock stop determination circuit, the refresh clock switching circuit switches from a selection of the refresh clock signal based on the reference clock to a selection of the self-refresh clock signal.Type: GrantFiled: August 17, 1992Date of Patent: May 17, 1994Assignee: Sharp Kabushiki KaishaInventor: Kouji Inoue
