Serial EEPROM (690)

ROHM serial EEPROMs are non-volatile memory optimized for data retention, available in a range of interfaces, package types, and storage capacities.

FeRAM (LAPIS)

FeRAM is Ferro-electric Random Access Memory from 32Kbit to 256Kbit configuration developed by ferroelectrics process and CMOS process technology.
No backup by battery, high speed random read/write, rewrite up to 1 trillion times and low power consumption are offered for various applications.
LAPIS Semiconductor's FeRAM ensures high quality and uninterrupted supply within ROHM group.

NOR Flash (LAPIS)

LAPIS Semiconductor is a manufacturer for NOR Flash memory in Japan. LAPIS Semiconductor's NOR Flash memory utilizes a floating gate structure. 128 Mb or less memory capacity is Single Level Cell(SLC). 256MB or more memory capacity is Multi Level Cell(MLC). Moreover bit error correction function by an ECC (Error Correction Code) circuit achieves superior data retention characteristics.

P2ROM (LAPIS)

LAPIS Semiconductor's read-only, non-volatile P2ROM™ products are specially designed to reduce lead time and eliminate stock at the customer's site while reducing programming costs and mask charges. A number of different models are available, from standard parallel and page mode units to SPI-compatible products and customizable memory (AS@P2ROM™) with built-in gate array.
