Abstract:
An ink jet print head identification system for providing print head identifying information to the electronics of an ink jet printer includes one or more parallel load, serial out, dynamic shift registers (50 A-D) integrated into a print head chip having a plurality of address lines interconnecting the printer electronics and print head electronics. Each shift register is programmed or encoded with a single digital bit. In one embodiment, a voltage pulse (load signal) (70) received on a single chip address line by a plurality of shift registers (50 A-D) loads the input of each encoded register with the register's own encoded bit. Two of the address lines (72,74) provide each of the registers with successive sequential clock signals (1,2) to serially shift the encoded information to an output device (80) where the print head identifying information is read by the printer electronics. Other embodiments of the invention may employ any number of encoded registers independently of the number of available address lines.
Abstract:
The semiconductor memory device can continuously read or store a plurality of data therefrom or therein. The semiconductor memory device includes a memory unit having a plurality of memory cells (3,4), the memory cells being arranged in a matrix having rows and columns, and a reading storing circuit. The reading storing circuit can read or store data from or into the memory cell at an address corresponding to an address signal received therein in response to the reception of first and second control signals, respectively. The reading storing circuit also can consecutively read or store data from or into the memory cell at another address subsequent to the address read or stored at the last time in response to the reception of the second control signal. Such a device can therefore have improved access time for continuous accessing of a plurality of data.

Abstract:
The present disclosure includes apparatuses and methods related to scatter/gather in a memory device. An example apparatus comprises a memory device that includes an array of memory cells, sensing circuitry, and a memory controller coupled to one another. The sensing circuitry includes a sense amplifier and a compute component configured to implement logical operations. A channel controller is configured to receive a block of instructions, the block of instructions including individual instructions for at least one of a gather operation and a scatter operation. The channel controller is configured to send individual instructions to the memory device and to control the memory controller such that the at least one of the gather operation and the scatter operation is executed on the memory device based on a corresponding one of the individual instructions.
Abstract:
The present disclosure includes apparatuses and methods related to data shifting. An example apparatus comprises a first memory cell coupled to a first sense line of an array, a first isolation device located between the first memory cell and first sensing circuitry corresponding thereto, and a second isolation device located between the first memory cell and second sensing circuitry corresponding to a second sense line. The first and the second isolation devices are operated to shift data in the array without transferring the data via an input/output line of the array.
Abstract:
A shiftable memory supporting bimodal data storage includes a memory having built-in shifting capability to shift a contiguous subset of data stored in the memory from a first location to a second location within the memory. The shiftable memory further includes a bimodal data storage operator to operate on a data structure comprising the contiguous subset of data words and to provide in-place insertion of a data value using the built-in shifting capability.
