  • Process and device for refreshing an array of dynamic memory cells during precharge of the column lines
    Patent number: 4831594
    Abstract: The device refreshes the cells of an array of dynamic memory cells a row at a time during precharging of the bit or column lines. Normal access to read or write to the cells also refreshes them. Refresh circuits connect to the row line between the row address decoder and the cells, and include shift register stages connected to the row lines. A bit of one sense shifting through the stages indicates the row to be refreshed and a refresh signal connected to the stages times the refresh during the precharge. Using multiple, sequential refresh signals refreshes alternating rows of the cells.
