Abstract
The integrated memory has a column decoder for decoding column addresses and for addressing corresponding bit lines. The memory also has a first column address bus, which is used to transfer first column addresses to the column decoder, and a second column address bus, which is used to transfer second column addresses to the column decoder. The column decoder in each case addresses bit lines which correspond to the first and second column addresses supplied to it.
Claims5
An integrated memory, comprising:
- a column decoder for decoding column addresses and for addressing corresponding bit lines;
- a first column address bus connected to said column decoder for transferring first column addresses to said column decoder;
- a second column address bus connected to said column decoder for transferring second column addresses to said column decoder;
- address input lines for receiving the first column addresses, said address input lines connected to said first column address bus for supplying the first column addresses thereto;
- an address counter for storing and incrementing a starting address to obtain the second column addresses, said address counter connected to said second column address bus for supplying the second column addresses thereto during a specific number of clock cycles of a clock signal applied to said address counter;
- and
- a control unit connected to said address input lines and to said address counter for loading one of the first column addresses into said address counter as the starting address;
- said column decoder for addressing bit lines according to the first and second column addresses received through said first and second column buses respectively.
