Examples of a printhead assembly comprising an Erasable Programmable Read-only Memory (EPROM) having a predefined number of banks, with EPROM cells arranged in rows and columns in each of the banks are described. In one example, the printhead assembly comprises a shift register to generate, in consecutive shift register cycles, a row select signal, column select signal, and bank select signal to select a row, column, and bank, respectively, corresponding to an EPROM cell. A row select signal bus, column select signal bus and bank select signal bus is included in the printhead assembly to provide the row select signal, column select signal, and bank select signal, respectively, to the EPROM cell during the respective shift register cycles.
