Title: Digital halftone printing method and system thereof
Inventor: RUISU ANSONII KAADEIRO
IPC: H04N1/23
Filed: 1991-12-27
Abstract: PURPOSE: To decide which system does not use mathematical operation and to limit data quantity stored in a lookup table by transmitting a write spot address signal to a means for generating an address pointer signal uniquely connecting with a specific write spot address code. CONSTITUTION: A clock 70 is used to control gates 72 and 74, and a spot line entry register 78 is updated only at the end of count corresponding to fully horizontal scan. The present spot address of a register 76 is supplied to lookup tables 84 and 80 and used to obtain a 1st value and a connecting pointer. A selective write step transmits the write spot address signal to a pointer lookup table for generating the address pointer signal uniquely connecting with the specific write spot address code, and transmits the address pointer signal to a write spot address register in order to obtain the next write spot address signal.

Title: Nonvolatile memory and memory system
Inventor: YUGAWA YOSUKE
IPC: G11C16/02
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To improve the service life of a memory and to enhance the reliability of data by adopting monitor bits that relate to each word line, have a smaller threshold margin than that of signals in other nonvolatile memory cells and reach earlier the end of service life. SOLUTION: A flush memory cell group 13 has a plurality of sectors (corresponding to words), and includes a data area 30 where a plurality of flush memory cell groups used for data read/write are laid out and a management area 40 to manage them. Monitor bits 3a, 3b in a sector 2 are formed in the management area 40 and the monitor bit 3a is referred to as a delete bit and the monitor bit 3b as a write bit. Since the monitor bits 3a, 3b have a smaller threshold margin in a data storage performance than that of memory cells in the data area 30, the data bits reach the end of service life earlier than that of the memory cells in the data area. Thus, the service life of a flush memory can be grasped by detecting occurrence of an error in the monitor bits.
