ORDERING INFORMATION

DESCRIPTION

The DS2223 and DS2224 EconoRAMs are fully static,

micro–powered, read/write memories in low–cost

TO–92 or SOT–223 packages. The DS2223 is orga-

nized as a serial 256 x 1 bit static read/write memory.

The DS2224’s first 32 bits are lasered with a unique ID

code at the time of manufacture; the remaining 224 bits

are static read/write memory. Signaling necessary for

reading or writing is reduced to just one interface lead.

able until the year 2003, at least.
