1. A memory device, comprising:
a memory array for storing at least one data bit and configured to electrically operate from a power supply voltage; and
a circuit configured to receive an external reference voltage as generated external to the memory device and generate in response thereto an internal reference voltage independent of the power supply voltage, the internal reference voltage for accessing and evaluating a logic state of the at least one data bit in the memory array.
2. The memory device of claim 1, further comprising data inputoutput circuitry coupled to the memory array and further coupled and responsive to the internal reference voltage of the circuit.
3. The memory device of claim 1, further comprising an address register coupled and responsive to the internal reference voltage of the circuit.
4. The memory device of claim 1, wherein the internal reference voltage generated by the circuit tracks follows the external reference voltage.
5. The memory device of claim 1, wherein the circuit comprises a following circuit configured to generate an internal reference voltage that is dependent upon the external reference voltage.
6. The memory device of claim 1, wherein the circuit comprises a voltage follower configured to receive the external reference voltage at an input and to generate in response thereto the internal reference voltage.
7. The memory device of claim 1, wherein the circuit comprises a plurality of voltage followers serially coupled to receive the external reference voltage and generate in response thereto the internal reference voltage.
8. The memory device of claim 1, further comprising circuitry for configuring the memory device as one of a DRAM, SDRAM, Rambus memory, double data rate memory and flash memory.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A chute extension device for dispensing a flow of mixed concrete, said device comprising:
a generally U-shaped extension body comprising an open top, a closed end, and an open end opposite said closed end and removably attached to and in fluid communication with a dispensing end of a concrete chute;
a funnel portion comprising a rectangular reservoir protruding from a bottom surface of and in fluid communication with said extension body, said rectangular reservoir comprising four inwardly sloping side walls for directing a flow of mixed concrete, each sidewall of said four sidewalls comprising a planar surface, a first sidewall of said four sidewalls extending proximate said closed end and being disposed at a non-zero first angle with respect to said bottom surface of said extension body, and a second sidewall of said four sidewalls longitudinally opposed to said first sidewall extending toward said open end and being disposed at a non-zero second angle with respect to said bottom surface of said extension body, said second angle being less than said first angle;
an upper aperture disposed through a lowermost portion of said rectangular reservoir and being configured to receive said flow of concrete from said four sidewalls, said aperture being located proximate said closed end of said extension body;
a funnel stem extending downwardly from and in fluid communication with said upper aperture;
a lower aperture disposed at a terminating end of said funnel stem;
a tubular boot connected to and in fluid communication with said funnel stem; and,
a boot orifice disposed at a terminating end of said boot for dispensing said flow of mixed concrete.
2. The device of claim 1, wherein said extension body further comprises an arcuate longitudinal member.
3. The device of claim 1, wherein said device further comprises a pair of hook features affixed to opposing upper corners of said extension body; and,
wherein said hook features removably engage a pair of receiving posts protruding from said dispensing end of a concrete chute.
4. The device of claim 1, wherein said device further comprises a boot clamp disposed over said boot for securing said boot to said funnel stem.
5. The device of claim 1, wherein said boot further comprises a rigid tubular member.
6. The device of claim 1, wherein said boot further comprises a flexible tubular sleeve.
7. The device of claim 3, wherein said device further comprises a boot clamp disposed over said boot for removably securing said boot to said funnel stem.
8. The device of claim 7, wherein said boot further comprises a rigid tubular member.
9. The device of claim 7, wherein said boot further comprises a flexible tubular sleeve.
10. The device of claim 4, wherein said device further comprises a pair of hook features affixed to opposing upper corners of said extension body open end; and,
wherein said hook features removably engage a pair of receiving posts protruding from said dispensing end of a concrete chute.
11. The device of claim 10, wherein said boot further comprises a rigid tubular member.
12. The device of claim 10, wherein said boot further comprises a flexible tubular sleeve.
