Abstract
The present invention relates to an apparatus for dividing a bank in a flash memory. A block of the flash memory is divided into two banks and each page buffer is located between the two banks to share an input/output line. Therefore, it is possible to shorten the length of a bit line, improve a data sensing rate, and allow one bank to perform one operation while the other bank performs a read, write or erase operation.
Claims4
An apparatus for dividing a bank in a flash memory, the flash memory having a first bank and a second bank that share an input/output line, comprising;
- a first page buffer connected to a bit line of the first bank, and buffering a data that will be transmitted to/from the first bank;
- a second page buffer connected to a bit line of the second bank, and buffering a data that will be transmitted to/from the second bank;
- a first page buffer select mean connected between the first page buffer and a first node, and controlling a transmission of the data that will be transmitted to/from the first page buffer;
- a second page buffer select mean connected between the second page buffer and the first node, and controlling transmission of the data that will be transmitted to/from the second page buffer;
- and
- a switching mean connected between the first node and the input/output line, and controlling transmission of the data between the first and second page buffer select mean and the input/output line.
