Abstract

A low power Read Only Memory (ROM) bank accessing system with efficient bust muxing is provided. The memory access system includes separate pre-charge and pre-discharge circuits for each bit lines in the ROM bank. In a ROM bank read operation, the pre-discharge circuits and pre-charge circuits are activated and deactivated in accordance with the address of the targeted ROM bank. In an exemplary embodiment, only the pre-charge lines corresponding to the bit-line of the targeted ROM bank are pre-charged prior to the ROM read operation. Similarly, only the pre-discharge circuit corresponding to the bit lines of the targeted ROM bank is deactivated during the ROM read operation, permitting the remaining bit lines from storing residual charge.
