CYM1441PZ-25C Description

The CYM1441 is a very high performance 2-megabit static RAM module organized as 256K words by 8 bits. The module is constructed using eight 256K x 1 static RAMs in SOJ packages mounted onto an epoxy laminate substrate with pins. Two chip selects (CS_L and CS_U) are used to independently enable the upper and lower 4 bits of the data word. Writing to the memory module is accomplished when the chip select (CS) and write enable (WE) inputs are both LOW. Data on the eight input pins (DI₀ through DI₇) is written into the memory location specified on the address pins (A₀ through A₁₇). Reading the device is accomplished by taking chip select (CS) LOW while write enable (WE) remains inactive or HIGH. Under these conditions, the contents of the memory location specified on the address pins will appear on the appropriate data output pins (DO₀ through DO₇). The data output pins remain in a high- impedance state unless the module is selected and write enable (WE) is HIGH.Two pins (PD₀ and PD₁) are used to identify module memory density in applications where alternate versions of the JEDEC-standard modules can be interchanged.
