Double byte select high voltage line for EEPROM memory block

A byte select circuit of a memory cell array wherein each column of the memory cell array has two byte select lines. A first byte select line is coupled to the even numbered rows in the column and a second byte select line is coupled to the odd numbered rows in the column. The second byte select line is configured to be driven to a low voltage level when the first byte select line is driven to a high voltage level, thereby minimizing or eliminating any parasitic voltage coupling between adjacent rows of memory cells.
