CY7C146-25JC集成电路（IC）的存储器规格书PDF中文资料

CY7C146-25JC属于集成电路（IC）的存储器。由赛普拉斯半导体公司制造生产的CY7C146-25JC存储器存储器是集成电路上用作数据存储设备的半导体器件。这些器件分为非易失性或易失性两种，格式包括 CBRAM、DRAM、EEPROM、EERAM、EPROM、闪存、FRAM、NVSRAM、PCM (PRAM)、PSRAM、RAM 和 SRAM。这些器件的存储容量为 64 b 至 6 Tb 不等，接口有 I2C、MMC、并行、eMMC、串行、单线、SPI、UFS、Xccela 总线和 1-线。

Functional Description

The CY7C132, CY7C136, CY7C136A, CY7C142, and CY7C146 are high speed CMOS 2K x 8 dual-port static RAMs. Two ports are provided to permit independent access to any location in memory. The CY7C132, CY7C136, and CY7C136A can be used as either a standalone 8-bit dual-port static RAM or as a MASTER dual-port RAM, in conjunction with the CY7C142/CY7C146 SLAVE dual-port device. They are used in systems that require 16-bit or greater word widths. This is the solution to applications that require shared or buffered data, such as cache memory for DSP, bit-slice, or multiprocessor designs.

特性 Features

■ True dual-ported memory cells that enable simultaneous reads of the same memory location

■ 2K x 8 organization

■ 0.65 micron CMOS for optimum speed and power
