Chip topography for a MOS disk memory controller circuit. |
摘要 |
<p>An improved chip topography for a disk memory controller circuit is provided which includes electrical interface circuitry disposed around the periphery of the chip and forming an approximately quadrilateral framework surrounding the remainder of the circuitry, a read-only-memory (ROM) disposed in one corner of the interface framework; a microcontroller disposed adjacent to the ROM and along part of a first side of the interface framework; read data processing circuitry disposed adjacent to the microcontroller and within a second corner of the interface framework and along part of a second side thereof; error checking circuitry disposed adjacent to the read data processing circuitry and along part of the second side of the interface framework; the microcontroller also being disposed adjacent to the error checking circuitry and along part of the second side of the interface framework; write data processing circuitry disposed adjacent to the microcontroller along the second side of the interface boundary, within a third corner of the interface framework and along a part of a third side of the interface boundary; the microcontroller also being disposed adjacent to the write data processing circuitry and along the third side of the interface framework; input/output (I/O) buffer/latch circuitry disposed adjacent to the micro controller along the third side of the interface framework, which is also disposed within the fourth corner and along a part of a fourth side of the interface framework, the microcontroller also being disposed adjacent to and between the I/O buffer/latch circuitry and the ROM along the fourth side of the interface framework; and task registers disposed between the microcontroller and the I/O buffer/ latch circuitry.</p> |
