CY14B102L, CY14B102N
2 Mbit (256K x 8/128K x 16) nvSRAM
Features Functional Description
■ 20 ns, 25 ns, and 45 ns Access Times The Cypress CY14B102L/CY14B102N is a fast static RAM, with
a nonvolatile element in each memory cell. The memory is
■ Internally organized as 256K x 8 (CY14B102L) or 128K x 16
organized as 256K bytes of 8 bits each or 128K words of 16 bits
(CY14B102N)
each. The embedded nonvolatile elements incorporate
QuantumTrap technology, producing the world’s most relia
