In one embodiment, this is a method of amplifying signals in a DRAM including sharing charge between a cell and a first conductor of a first pair of complementary conductors; and driving a voltage of the first conductor of the first pair and a voltage of a second conductor of the first pair in the same direction relative to a power supply voltage. In an alternate embodiment, this is an apparatus. The apparatus includes a first transistor having a first terminal, a second terminal and a gate. The apparatus also includes a second transistor having a first terminal, a second terminal and a gate, the gate of the second transistor coupled to the first terminal of the first transistor, the first terminal of the second transistor coupled to the gate of the first transistor. Moreover, the apparatus also includes a third transistor having a first terminal, a second terminal, and a gate, the first terminal of the third transistor coupled to the second terminal of the first transistor and the second terminal of the second transistor, the gate of the third transistor coupled to a power enable conductor, the second terminal of the third transistor coupled to a power supply node. In another alternate embodiment, this is a DRAM cell array.

JMOS Technology, Inc. - Fremont CA

International Classification:

G11C 800

US Classification:

365233, 36518901, 365222

Abstract:

A method and apparatus for asynchronously controlling a DRAM array in an SRAM environment is described. In on embodiment, this is a method of arbitrating between a refresh request and an access request. Furthermore, the access request may be either a read or a write request. Moreover, the request may be generated by a refresh control circuit within a circuit implementing the asynchronous control method. In an alternate embodiment, this is an apparatus. The apparatus includes an arbitration circuit block which may receive a refresh request and an access request. Furthermore, the access request may come as a read request or a write request, which may be implemented as separate signals. Moreover, the apparatus may include a refresh circuit block which may generate refresh control signals and the refresh request signal for the arbitration circuit.

Abstract:

An implantable glaucoma drainage device (GDD) system is disclosed. The GDD system comprises a microflow control system for controlling intraocular pressure, a protective capillary carrier tube housing the microflow control system, and anchoring arms holding the implanted device in place. The overall GDD size can be in a needle-implantable form factor for minimally invasive implantation. The GDD may be implanted via subconjunctival needle implantation to mimic the normal aqueous humor drainage pathway.
