2048 WORD BY 8 BIT BIPOLAR TTL
PROGRAMMABLE READ ONLY MEMORY
DESC RIPT ION
The JlPB409 and JlPB429 are high-speed, electrically programmable, fully-decoded
16384 bit TTL read only memories. On-chip address decoding, three chip enable
inputs and open-collector/three-state outputs allow easy expansion of memory
capacity. The JlPB409 and JlPB429 are fabricated with logic level zero (low); logic
level one (high) can be electrically programmed into the selected bit locations. The .
same address inputs are used for both programming and reading.
FEATURES
• 2048 WORDS x 8 BITS Organization (Fully Decoded)
