M27C400屬于集成電路（IC）的存儲(chǔ)器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的M27C400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 M27C400 is an 4 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems requiring large data or program storage. It is organised as either 512 Kwords of 8 bit or 256 Kwords of 16 bit. The pin-out is compatible with the most common 8 Mbit Mask ROM.
