CY14B104L, CY14B104N
4 Mbit (512K x 8/256K x 16) nvSRAM
Features Functional Description
■ 20 ns, 25 ns, and 45 ns Access Times The Cypress CY14B104L/CY14B104N is a fast static RAM, with
a nonvolatile element in each memory cell. The memory is
■ Internally organized as 512K x 8 (CY14B104L) or 256K x 16
organized as 512K bytes of 8 bits each or 256K words of 16 bits
(CY14B104N)
each. The embedded nonvolatile elements incorporate
QuantumTrap technology, producing the world’s most reliable
■ Hands
