Abstract:
An ink jet print head identification system for providing information to the electronics (98) of an ink jet printer includes a plurality of shift registers (92) having a plurality of address lines. The memory input of each shift register is electrically connected to a memory matrix that supplies digital bits of information to the shift registers (92) in response to receiving a decode input signal (94).
Abstract:
A sense amplifier (200) for use in a serial configuration memory includes multiple stages which are enabled and disabled in a controlled manner (270), in response to a control pulse (SAEN). The control pulse (SAEN) is produced every Nth period of an externally provided clock signal, the clock being used to clock out a bitstream representing the contents of the memory device. In a preferred embodiment, N such sense amps (200) are utilized to read out in parallel fashion the N memory cells (bits) comprising an accessed memory location. The sense amps (200) are therefore active only of a period of time sufficient to read out a memory cell.

A memory (200) is provided which includes a plurality of self-contained memory units (201) for storing data. A plurality of shift registers (211) are provided, each including a first parallel port coupled to a data port of a corresponding one of the self-contained memory units (201). Interconnection circuitry (212) is coupled to a parallel data port of each of the shift registers. Control circuitry (208, 213) is provided which is operable to control the exchange of data between a selected one of the memory units and the interconnection circuitry (212) via the shift register (211) coupled to the selected memory unit (201).

Abstract:
PROBLEM TO BE SOLVED: To achieve a high read-out rate of data while suppressing an increase in circuit size in a serial interface memory device. SOLUTION: An EEPROM (Electrically Erasable PROM) 100 includes: a memory cell array 10 storing data; a row address decoder 11 and a column address decoder 12 that select an address of the memory cell array 10 according to an address signal serially input in synchronization with a clock; sense amplifiers SA0 to SA5, SA_M0, and SA_M1 each provided in association with each bit of the data; and a shift register 15 that outputs data read out from the sense amplifiers serially from a first bit in synchronization with the clock. The column address decoder 12 commences reading out two candidate data for the first bit by inputting the two candidate data to the sense amplifiers SA_M0 and SA_M1, respectively before all bits of the column address signal are established.

Abstract:
PURPOSE: To solve the incapability of the 1-bit shift produced when the working speed is increased with a VRAM incorporating the shift register of the 1-word segment containing the master-slave constitution of each stage, by dividing the shift register into plural columns. CONSTITUTION: Transfer gates T 3 and T 4 are added to attain the connection of odd colum SR1, SR3,... and even column SR2, SR4,... of a shift register to the odd and even bit lines respectively. In the same way, the dummy cells DC are also connected to the odd and even bits. The transfer gates T 1 WT 4 are selected by exclusive transfer clocks TR1 and TR2. That is, the gates T 3 and T 4 are turned on by setting clocks TR2 and TR1 at H and L respectively. Then the odd bit lines are connected to columns SR2, SR4,... together with the even bit lines connected to columns SR1, SR3,... respectively (reverse mode). Thus the incapability of the 1-bit shift can be solved in said reverse mode. COPYRIGHT: (C)1986,JPO&Japio
