ADDRESSING AN EPROM ON A PRINTHEAD |
| 摘要 |
Addressing an EPROM on a printhead is described. In an example, a printhead includes an electronically programmable read-only memory (EPROM) having a plurality of cells arranged in rows and columns, each of the cells having a addressing port, a row select port, and a column select port. A conductor is coupled to the addressing portion of each of the plurality of cells, A column shift register is coupled to the column select ports of the plurality of cells, the column shift register having a register location for each column of the plurality of cells and having an input to receive a first input signal. A row shift register is coupled to row select ports of the plurality of cells, the row shift register having a register location for each row of the plurality of cells and having an input to receive a second input signal. |
