Abstract
Dual port memory blocks that have a reduced layout area are provided. The write drivers and sense amplifiers are shared between the dual ports to reduce the number of write drivers and sense amplifiers to save layout area. The write drivers for the two ports are used to write into all of the first port's bitlines. The sense amplifiers for the two ports are used to read from all of the second port's bitlines. A memory block can to support true dual port (TDP) and simple dual port (SDP) operation using substantially less write drivers and sense amplifiers.
