Self timed memory chip having an apportionable data bus

Image Number 10 for United States Patent #7546410.

A self timed memory chip having an apportionable data bus. Access timing to an array on the memory chip is dynamically determined by circuitry on the memory chip. A ring oscillator on the memory chip has a frequency that is indicative of how fast an array on the memory chip can be accessed. The ring oscillator includes a bit line that is periodically charged and a memory element that subsequently discharges the bit line. The memory chip has a data bus interface having a number of bits. The data bus interface has a first number of bits apportioned to write data and a second number of bits apportioned to read data. The first number of bits and the second number of bits is programmable.
