摘要： A seal system between a row of buckets supported on a machine rotor and a surrounding stationary casing or stator includes a tip shroud secured at radially outer tips of each of the buckets, the tip shroud formed with a radially-projecting rail. A cellular seal structure is supported in the stationary stator in radial opposition to the tip shroud and the rail. The seal structure has an annular array of individual cells formed to provide continuous, substantially horizontal flow passages devoid of any radial obstruction along substantially an entire axial length dimension of the cellular seal structure to prevent flow about the tip shroud from turning radially inwardly.

The memory device includes a memory array, one or more address decoders, a word line driver, a plurality of sense amplifiers, a reference word line column, a reference bit line column, and a control circuit. The control circuit generates a control signal to perform read and write operations on the memory device. The address decoder selects a bit line and a word line. The selected word line is activated by the word line driver. While the reference word line column is used for vertical tracking of the word line, the reference bit line column is used for vertical tracking of the bit line. The sense amplifiers are activated to read the bit line.

A reference word line is enabled based on the programmable precharge signal and the control signals for tracking the enabled word line. A reference bit line is enabled based on the reference word line for tracking the enabled bit line. The reference sense generator generates a programmable sense signal based on the reference bit line, the programmable precharge signal and the control signals for reading a bit cell corresponding to the enabled bit line and word line.
