摘要 |
A dual-port memory device for split data transfer comprises: a first normal memory pan comprising a first RAM 20, a first SAM 22 and a first transfer gate 24 connected for memory data transfer between them, a second normal memory pan comprising a second RAM 30, a second SAM 32 and a second transfer gate 34 connected for memory data transfer between them; a transfer memory signal generator 40 for providing first and second transfer signals to the first and second transfer gates respectively; and a redundant memory 50 comprising a redundant RAM 60, a redundant SAM 62, a redundant transfer gate 64 and a redundant transfer signal generator 70 for selecting one of the first and second transfer signals so that if a defect arises in either memory pan the redundant memory can substitute therefor. <IMAGE> |
