Abstract:
With a serial interface memory device of this invention, a read-out rate of data is increased, while an increase in a size of a circuit is suppressed. An EEPROM is provided with a memory cell array storing data, a row address decoder and a column address decoder that select an address of the memory cell array in accordance with an address signal serially inputted in synchronization with a clock, sense amplifiers SA0-SA5, SA_M0 and SA_M1 each provided corresponding to each bit of the data, and a shift register that outputs the data read out from the sense amplifiers serially from a first bit. The column address decoder commences reading out two candidate data for the first bit by inputting each of the two candidate data to each of the two sense amplifiers SA_M0 and SA_M1, respectively, before all bits of the column address signal are established.

PROBLEM TO BE SOLVED: To provide an inexpensive device, capable of increasing the amount of information stored in a printing head cartridge without increasing the number of address lines or complicating the printing head electronics. SOLUTION: A memory device for storing and outputting information includes a plurality of memory matrices, each of which includes a plurality of transistors having a drain, a source and a gate, arranged in various levels from the minimum level to the maximum level. Furthermore, the device includes a plurality of single bit shift resistors for producing a consecutive output, and it has a memory input and a memory matrix related therewith. The memory input is connected electrically with the source of the transistor of the maximum level of the memory matrices. The memory device includes a plurality of address lines for receiving a decoding signal function, a loading signal, and a clock signal, and an outputting line for transmitting the consecutive output of the plurality of the shift resistors.

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 processor includes N-bit registers and a decode unit to receive a multiple register memory access instruction. The multiple register memory access instruction is to indicate a memory location and a register. The processor includes a memory access unit coupled with the decode unit and with the N-bit registers. The memory access unit is to perform a multiple register memory access operation in response to the multiple register memory access instruction. The operation is to involve N-bit data, in each of the N-bit registers comprising the indicated register. The operation is also to involve different corresponding N-bit portions of an MxN-bit line of memory corresponding to the indicated memory location. A total number of bits of the N-bit data in the N-bit registers to be involved in the multiple register memory access operation is to amount to at least half of the MxN-bits of the line of memory.
Abstract:
Apparatus and methods of operating memory devices are disclosed. In one such method, a first portion of the data states of memory cells are determined and transferred from a memory device while continuing to determine remaining portions of data states of the same memory cells. In at least one method, a data state of a memory cell is determined during a first sense phase and is transferred while the memory cell experiences additional sense phases to determine additional portions of the data state of the memory cell.
