Patent JP-H05182491-A (JP)
Title: Nonvolatile semiconductor storage device
Inventor: HASHIMOTO KIYOKAZU
IPC: G11C29/04
Filed: 1991-12-27
Abstract: PURPOSE:To suppress a scale of a replacement circuit which replaces a defective cell with a redundant cell, even if numbers of sector increase. CONSTITUTION:When a storage element judged as a defective cell is included in any sector among the sector 1 to 8, a replacement circuit replaces a digit line to which a defective storage element is connected with a redundant digit line within the redundant cell region 1. When a storage element judged as a defective cell is included in any sector among the sector 9 to 16, a replacement circuit replaces a digit line with a redundant digit line within the redundant cell region 2. Thus, since one redundant region is provided for plural sectors, the scale of the replacement circuit is smaller than in the conventional method.
