  • Publication number: 20110131472
    Abstract: Systems and methods are provided that confront the problem of failed storage integrated circuits (ICs) in a solid state drive (SSD) by using a fault-tolerant architecture along with one error correction code (ECC) mechanism for random/burst error corrections and an L-fold interleaving mechanism. The systems and methods described herein keep the SSD operational when one or more integrated circuits fail and allow the recovery of previously stored data from failed integrated circuits and allow random/burst errors to be corrected in other operational integrated circuits. These systems and methods replace the failed integrated circuits with fully functional/operational integrated circuits treated herein as spare integrated circuits. Furthermore, these systems and methods improve I/O performance in terms of maximum achievable read/write data rate.

  • Patent number: 7924525
    Abstract: Drive circuitry for driving a load through a connection to a transmission line, such as for driving the write head of a hard disk drive. A hybrid termination is provided for termination at the connection to the transmission line. The termination is hybrid since there is both an in-series and an in-parallel component to the termination resistance. In addition, in embodiments where there is matched termination of the transmission line during a boost period of driving the load, the termination is hybrid since the termination is switched between a boost period of a write operation, and a steady state period of the write operation.

  • Patent number: 7868658
    Abstract: A circuit comprises first and second buffers, and an output buffer. The first buffer receives an input signal and provides a first buffer output signal on a first lead. The second buffer receives the input signal and provides a second buffer output signal on a second output lead. The output buffer has a first input lead coupled to the first output lead and AC coupled to the second output lead. The AC coupling communicates timing information from the second buffer to the output buffer. The first buffer applies sufficient voltage to control the first input lead of the output buffer under DC conditions.

  • Patent number: 7848038
    Abstract: A driver for driving a load over a transmission line, such as driving the magnetic head of a hard disk drive. The driver includes a signal switch for switching the signal to the load during a signal period, and a boost switch for boosting the signal during a boost period, so as to decrease rise time of the signal at the load by deliberately injecting an overshoot. A switchable protection device protects the signal switch and the boost switch. The protection device includes a reflection-suppression switch which is pulsed during a time corresponding to the expected return of a reflection corresponding to the overshoot signal, so as to force the protection device into saturation mode. Since the protection device is in the saturation mode during the return reflection of the boost signal, the returned reflection sees a matched impedance and thus reduces a re-reflection back to the load.
