CAT24C44屬于集成電路（IC）的存儲(chǔ)器。由安森美半導(dǎo)體公司制造生產(chǎn)的CAT24C44存儲(chǔ)器存儲(chǔ)器是集成電路上用作數(shù)據(jù)存儲(chǔ)設(shè)備的半導(dǎo)體器件。這些器件分為非易失性或易失性兩種，格式包括 CBRAM、DRAM、EEPROM、EERAM、EPROM、閃存、FRAM、NVSRAM、PCM (PRAM)、PSRAM、RAM 和 SRAM。這些器件的存儲(chǔ)容量為 64 b 至 6 Tb 不等，接口有 I2C、MMC、并行、eMMC、串行、單線、SPI、UFS、Xccela 總線和 1-線。

DESCRIPTION

The CAT24C44 Serial NVRAM is a 256-bit nonvolatile memory organized as 16 words x 16 bits. The high speed Static RAM array is bit for bit backed up by a nonvolatile EEPROM array which allows for easy transfer of data from RAM array to EEPROM (STORE) and from EEPROM to RAM (RECALL). STORE operations are completed in 10ms max. and RECALL operations typically within 1.5μs. The CAT24C44 features unlimited RAM write operations either through external RAM writes or internal recalls from EEPROM. Internal false store protection circuitry prohibits STORE operations when VCC is less than 3.5V (typical) ensuring EEPROM data integrity.
