摘要： A method and apparatus are provided for high performance, high voltage memory operations on selected memory cells (200) of a semiconductor memory device (100). A high voltage generator (106) during program or erase operations provides a continuous high voltage level (702) on selected word lines (502) and maintains a continuous high voltage level supply to a bit line decoder (120) which sequentially provides the high voltage level (706) to a first portion of bit lines (504) and discharges (708) those bit lines (504) before providing the high voltage level to a second portion (710). For additional improvements to program operations, the high voltage generator (106) decouples high voltages provided to the word lines (502) and the bit lines (504) by providing a current flow control device (1208) therebetween and provides a boosting voltage at a time (1104) to overcome a voltage level drop (1102) resulting from a capacitor load associated with selected bit lines (504) and/or the bit line decoder (120) precharges (1716) a second portion of the bit lines (504) while providing a high voltage level to a first portion to program (1706) a first portion of memory cells (200). For improvements to read operations, whether dynamic reference cells (2002) are blank is determined by providing non-identically regulated high voltage levels from a first voltage source (2112) to the dynamic reference cells (2002) and from a second voltage source (2104) to static reference cells (2004) and, if the dynamic reference cells (2002) are not blank, reads selected memory cells (200) by providing identically regulated high voltage levels to the selected memory cells (200), the dynamic reference cells (2002) and the static reference cells (2004).

摘要： A method and apparatus are provided for improved noise reduction from switching on and off drain pumps (202) in a high voltage generator. The drain pumps (202) are divided into groups (204) and activation of the groups (204) of drain pumps (202) is staggered (304, 310). In addition, when drain pumps are switched on and off for power conservation or to maintain a steady state high voltage level, the groups (204) of drain pumps (202) are switched on and off in response to various predetermined high voltage levels (410, 412, 414, 416), with different voltage levels for different groups (204) of drain pumps (202).

摘要： A physical layer transceiver of a home network station connected to a telephone medium has an architecture enabling adaptation of detection circuitry based on received network signals to enable reliable recovery of data signals. The physical layer transceiver includes an input amplifier that amplifies network signals according to one of 128 gain settings set by a receiver gain control signal. A signal conditioning circuit includes an envelope detector configured for outputting an envelope of the amplified received signal, and an energy detector configured for outputting an energy signal of the amplified received signals. The envelope signal and the energy signal are supplied to slicer threshold circuits, configured for outputting noise, peak, data event and energy event signals based on noise threshold, peak threshold, data transition threshold, and energy threshold signals, respectively. A digital controller controls the input amplifier gain and the threshold values, and adjusts the gain and threshold values based on the noise event signal and the peak event signal within an access ID (AID) interval. Hence, the receiver can be optimized on a per-packet basis for receiving network signals by adjusting the receiver portion during the AID preamble phase of the data packet. Gain control may also be used by the digital controller on the transmitter portion to selectively adjust the output gain for optimizing transmission to a destination home network station.
