Dear customer st LAPIS Semiconductor Co., Ltd. LAPIS Semiconducto), on the 1 day of October, 2020, implemented the incorporation-type company split (shinsetsu-bunkatsu) in which LAPIS established a new company, LAPIS Technology Co., Ltd. (LAPIS Technology) and LAPIS Technology succeeded LAPIS Semiconductors LSI business. Therefore, all references toLAPIS Semiconductor Co., Ltd,LAPIS Semiconducto and/orLAPI in this document shall be replaced withLAPIS Technology Co., Ltd Furthermore, there are no changes to the documents relating to our products other than the company name, the company trademark, logo, etc. Thank you for your understanding. LAPIS Technology Co., Ltd. October 1, 2020 FEDR45VV100A-01 Isssue Date: Sep. 4, 2017 MRR45V1100A 1M Bit((131,072-Worrd 8-Bit) FeRRAM (Ferroellectric Randomm Access Memmory) SPI GENERRAL DESCRRIPTION The MR445V100A is aa nonvolatile 1128Kword x 88-bit ferroelecctric random aaccess memorry (FeRAM) developed in the feerroelectric prrocess and sillicon-gate CMMOS technoloogy. The MRR45V100A is s accessed using Serial Peripheraal Interface. UUnlike SRAMss, this device, whose cells aare nonvolatilee, eliminates bbattery backupp required to hold ddata. This devvice has no mmechanisms off erasing and programmingg memory ceellls and blockks, such as those useed for variouss EEPROMs. Therefore, the write cycle time can be equal to the rread cycle timme and the power coonsumption duuring a write ccan be reducedd significantlyy. The MR445V100A can be used in vaarious applicattions, becausee the device is guaranteed foor the write/reead 12 tolerance of 10 cycles per bit and tthe rewrite couunt can be exttended significcantly.
