SpectralMemory

Revolutionary memory management using Riemann zeta zeros for intelligent, self-organizing allocation

What is SpectralMemory?

SpectralMemory is a complete memory management system that treats computation and memory as spectral phenomena. Instead of traditional linear address spaces, it uses frequency-based addressing where each memory location corresponds to a resonance frequency derived from Riemann zeta zeros.

This enables revolutionary capabilities:

🔥 Automatic thermal management: Hot data migrates to fast cache, cold data to efficient storage
🧮 Mathematical coherence: Built on proven number theory (ideal class groups, spectral theory)
📊 Self-organizing: No manual tuning—learns your access patterns automatically
🔬 Research-grade: Explores connections to the Riemann Hypothesis and quantum computing

Quick Start

# Install in development mode
pip install -e .

# Run the minimal system demo(simplest interface)
python -c "from spectral_memory.minimal.spectral_memory_minimal import demo; demo()"

Basic Usage (Minimal System)

from spectral_memory.minimal.spectral_memory_minimal import ThermalDict

# Use like a regular dictionary - thermal management is automatic
mem = ThermalDict()

# Store data
mem["cache"] = expensive_computation()
mem["config"] = {"theme": "dark"}

# Access patterns are tracked automatically
for i in range(1000):
    result = mem["cache"]  # Frequent access → becomes "hot"

# View thermal distribution
print(mem.thermal_status())
# Output: {'hot': 1, 'warm': 0, 'cold': 1}

Advanced Usage (Hierarchical System)

from spectral_memory.hierarchical.spectral_malloc_hierarchical import (
    HierarchicalSpectralMemory,
    SMEM_HOT
)

mem = HierarchicalSpectralMemory(n_zeros=100)

# Allocate with explicit thermal hint
cache_id = mem.malloc(size=1024, temperature=SMEM_HOT, t_virtual=180.0)

# Simulate access pattern
for _ in range(1000):
    mem.access(cache_id)

# Free (triggers automatic thermal migration if needed)
mem.free(cache_id)

# View comprehensive statistics
stats = mem.get_stats()
print(f"Mean mismatch: {stats['mean_mismatch']:.4f}")
print(f"Migrations: {stats['migrations']}")

Two Implementations

SpectralMemory provides two complementary approaches for different use cases:

1. Minimal System (`spectral_memory.minimal`)

For developers who want simple, automatic thermal management.

The minimal system provides a dictionary-like interface that automatically organizes data based on access patterns. No complex math required.

Key Features:

📦 Drop-in replacement for Python dictionaries
🌡️ Automatic hot/cold data classification
📡 20 frequency bands from Riemann zeta zeros
📝 ~500 lines of clean, documented code

Use When:

You want automatic memory optimization without learning the underlying theory
Building caches, session stores, or data structures with access patterns
Prototyping thermal-aware systems

2. Hierarchical System (`spectral_memory.hierarchical`)

For researchers and systems architects building scalable memory systems.

A complete two-level addressing architecture with 2³² local addresses per zeta zero.

Structure:

3 axes: Zero vector (0), Real (1), Imaginary (2)
7 primes: {2, 3, 5, 7, 11, 13, 17} for multiplicative channels
12 lattices: Ideal class group (h=12) for coherence guarantees
100 zeta zeros: ~400GB virtual address space

Key Features:

🏗️ Industrial-scale architecture with mathematical coherence
🔒 Guaranteed non-interference (via ideal class theory)
🌡️ Multi-level thermal hierarchy (hot/warm/cold/ultra-cold)
📏 Explicit quantization and mismatch tracking

Use When:

How It Works

The Core Idea: Resonance-Based Addressing

Traditional memory allocators use linear byte addresses:

malloc(1024) → 0x7f12345678 (just a number)

SpectralMemory uses frequency addresses from Riemann zeta zeros:

malloc(1024, SMEM_HOT, t_virtual=180.0)
  ↓
Quantizes to nearest resonance: 179.92
  ↓
Stores at that frequency with tracked mismatch: 0.08

Why Zeta Zeros?

The imaginary parts of Riemann zeta zeros form a natural discrete frequency spectrum:

𝓣 = {14.13, 21.02, 25.01, 30.42, ..., 236.52}  (first 100)

These frequencies have special properties:

Well-separated: Clear distinction between hot (high freq) and cold (low freq)
Mathematically complete: If the Riemann Hypothesis is true, they form a complete basis
Automatic hierarchy: Frequency naturally encodes thermal regime

Two Regimes

STM (Short-Term Memory): High frequencies (>100)

Narrow Voronoi cells
Phase-coherent (Mellin transform)
Fast access, expensive to maintain

LTM (Long-Term Memory): Low frequencies (<30)

Wide Voronoi cells
Entropy-bound (coarse-grained)
Slow access, cheap to maintain

Thermal Migration: Data automatically moves between regimes based on access patterns.

Examples

Example 1: Session Storage with Auto-Thermal

from spectral_memory.minimal.spectral_memory_minimal import ThermalDict

# Create thermal-aware session store
sessions = ThermalDict()

# Active user - accessed frequently
sessions["user_123"] = {"last_active": time.time(), "token": "..."}
for _ in range(100):
    sessions["user_123"]  # Frequent access → becomes hot

# Inactive user - rarely accessed
sessions["user_456"] = {"last_active": old_time, "token": "..."}

# Thermal distribution adapts automatically
print(sessions.thermal_status())
# {'hot': 1, 'warm': 0, 'cold': 1}

Example 2: Multi-Tier Cache Hierarchy

from spectral_memory.hierarchical.spectral_malloc_hierarchical import (
    HierarchicalSpectralMemory,
    SMEM_HOT, SMEM_COLD
)

mem = HierarchicalSpectralMemory(n_zeros=100)

# L1 cache equivalent (hot, high frequency)
l1_cache = mem.malloc(64, SMEM_HOT, t_virtual=220.0)

# L3 cache equivalent (warm, medium frequency)
l3_cache = mem.malloc(512, SMEM_AUTO, t_virtual=100.0)

# Disk cache equivalent (cold, low frequency)
disk_cache = mem.malloc(4096, SMEM_COLD, t_virtual=15.0)

# System automatically maintains thermal hierarchy
stats = mem.get_stats()
print(f"STM blocks: {stats['stm_blocks']}")
print(f"LTM blocks: {stats['ltm_blocks']}")

Example 3: Data Structure with Thermal Awareness

from spectral_memory.hierarchical.data_storage_example import demo_data_storage

# See complete example of:
# - Creating thermal-aware data stores
# - Automatic promotion of hot data
# - Demotion of cold data

Mathematical Foundation

Riemann Hypothesis Connection

Riemann Hypothesis: All nontrivial zeros of ζ(s) have Re(s) = 1/2.

In SpectralMemory terms:

Each zero γₙ determines addressing for one "band"
The zeros form a complete set for global coherence
If RH is true → system is optimal and complete
If RH is false → system would have "orphaned" addresses

Speculation: Could RH be equivalent to "zeta zero structure provides optimal addressing"?

Ideal Class Theory (h=12)

The hierarchical system uses ideal class groups with class number h=12 to guarantee non-interference:

Two allocations in different lattice sectors cannot interfere
(mathematically guaranteed by algebraic number theory)

This eliminates the need for traditional cache coherence protocols—coherence is built into the addressing scheme.
