Abstract
A read-only memory includes an array of rows and columns of memory cells with row lines and column lines associated with the array. The row lines are partitioned into groups that provide bits of a word on a number of output lines. Each group consists of an output line and a first voltage line with a plurality of row lines in between. A row selector is provided that receives an address signal for selecting a particular row in each group and connects a row line on one side of the selected row to the first voltage line and connects the row line on the other side of the row to the output line. A row precharge circuit is provided for precharging the row lines prior to the connection of a row line to an output line. Also provided is a column select circuit for receiving an address signal for connecting a particular column line to a second voltage line and for connecting one or more of the remaining column lines to one of the first voltage lines in order to reduce coupling.
